    Safe Use of Badge Magnet

    Want to buy name tags for your company’s employees? Make sure to get a sustainable name badge and provide employees with a quick and convenient way to identify themselves to customers and customers. Badge magnet is by far the most popular style. Among the many brand-name fastener fasteners we provide, magnets are most suitable for wearing professional clothing because they will not leave holes or tears like traditional pins. If you want to ensure that employees wear name tags that will not be lost, these magnets can provide important protection for all types of clothing. Here are the most frequently asked questions about our badge magnets: How does the badge magnet work? After using our design tool to design your name badge, please select magnet as your support type. Depending on your choice, the metal strip is firmly coated on the back of the plastic or metal name tag with a durable adhesive. These are very convenient and can be easily switched and used without leaving holes in the clothes. The blue plastic strip with 3 powerful magnets can attach the name badge to all types of clothes, whether it is a thin business shirt or a wool suit jacket. Are badge magnets harmful? Magnets are potentially harmful, yes. The blue plastic strip containing 3 round magnets has the warning to remind anyone with a pacemaker not to use magnets. "Warning-magnetic equipment, do not use it with pacemakers." If you are responsible for ordering name tags for office workers, be sure to pay attention to employees who have pacemakers. What happens when you put a magnet on the pacemaker? It is well known that magnets can interfere with pacemakers and suppress the treatment of arrhythmia. Magnets are not recommended for people with pacemakers. Please consult your doctor before using magnetic equipment. Find more information about magnets and pacemakers here. Will magnets harm the computer? When the magnet is close to the computer's hard drive, its magnetic field can damage the hard drive and destroy its contents. Badge magnets are generally safe and do not come into close contact with the computer hard drive. Thank you for reading our article. Ningbo Tengxiao Magnetic Industry Co., Ltd. not only has badge magnets but also pot magnets and other products. Welcome customers at home and abroad to come to discuss cooperation.
  2. A question that many customers ask before placing an order for neodymium ring magnets is, how many days does it take for your bulky goods to be delivered? Next, we will introduce the production cycle and time-consuming process of the neodymium ring magnets. What are the steps required to produce ring neodymium magnets? The first is the preparation of materials. It takes at least one day to purchase raw materials and inspect whether they are qualified. The second is punching. Use a punching machine to punch the inner holes of the blanks that have passed the inspection. Metal punching progress is slow. If it is a countersunk hole, there is one more process, which is to punch the straight hole first and then the counter hole. The third is slicing. After punching, the blank is put into a slicer for slices. The fourth is chamfering. The cut black pieces are chamfered into the chamfering machine (no electroplating is possible without chamfering, or the electroplated surface is easy to fall off). The fifth is electroplating. The finished product will be sent to the electroplating factory for electroplating. The sixth is magnetization and packaging. I believe that after reading it, you will have a certain understanding of a cycle of neodymium ring magnets production. Ningbo Tengxiao Magnetic Industry Co., Ltd. not only has neodymium ring magnets, but also custom industrial magnets and other products. Welcome customers at home and abroad to come to discuss cooperation.

    Uses of NdFeB Magnets

    Neodymium is a mixed metal (mixed metal) of rare earth metal components that can be used to make powerful magnets. NdFeB magnets boron magnets are best known for their mass, even a small magnet can withstand loads thousands of times its own weight. Although neodymium is a "rare" rare earth metal, neodymium has a wide range of uses, so it is easy to obtain raw materials for manufacturing NdFeB magnets. Due to its strength, neodymium iron boron magnets can be widely used in applications such as jewelry, toys, and computer equipment. NdFeB magnets (also called NIB magnets) are measured with a magnetic scale from N24 to N55, and the magnetic scale is up to N64, which is a theoretical magnetic measurement. Depending on the shape, composition, and production method, NIB magnets may fall anywhere within this range and provide a serious boost in strength. In order to make a nova (sometimes called a "nova"), manufacturers collect rare earth metals and screen them to find usable neodymium, which they must separate from other minerals. This neodymium is ground into fine powder, mixed with iron and boron, and can be resealed into the desired shape. The official chemical name of neo is Nd2Fe14B. Because of the iron in iron, it has similar properties to other ferromagnetic materials, including mechanical brittleness. Sometimes this can cause problems because the magnetic force is very large, and if the neo connection is too fast and has a lot of momentum, it may break or break on its own. Because neodymium iron boron magnets are very strong, they have a wide range of uses. They are produced for commercial and industrial needs. For example, something as simple as a piece of magnetic jewelry uses neodymium to hold the earrings in place. At the same time, neodymium magnets are sent into space to help collect dust from the surface of Mars. The dynamic properties of NdFeB magnets even lead to their use in experimental suspension equipment. In addition to these, NdFeB magnets are also used in welding fixtures, oil filters, treasure hunts, installation tools, clothing, and other applications. Ningbo Tengxiao Magnetic Industry Co., Ltd. not only has a strong NdFeB magnet but also products such as office magnets. Welcome to contact us.

    Introduction to Permanent Magnet

    Permanent magnets are unique components in the energy conversion process. They usually operate in a dynamic cycle, in which energy is converted from electrical or mechanical form to field energy, and then back to its original form. This process is crucial because permanent magnets are part of almost all the most important products in our lives. With the emergence of new methods of manufacturing permanent magnets and new markets driving demand for better magnets, permanent magnets have begun to change. One of the main advancements in permanent magnets, and one of the most important advances, is the ability to produce permanent magnets through additive manufacturing. Magnets can be produced without any tools, and there is very little waste, which opens up many design opportunities. In fact, researchers recently announced that permanent magnets produced by additive manufacturing are superior to traditional bonded magnets and produce less waste. Additive manufacturing creates new functions in permanent magnets. Thanks for reading our article. Ningbo Tengxiao Magnetic Industry Co., Ltd. specializes in the production of permanent magnet components and other products. If you are interested, please contact us.

    How to Use Countersunk Magnets?

    You may be more familiar with countersunk magnets than you think. These ring magnets look like washers with a raised surface and a hole in the middle. There are wedges and holes, so a countersunk magnet (also called a countersunk magnet) can be anchored in place with a single screw. We provide you with several ways to use countersunk magnets, which can make everything around the house easier. Magnetic latch If you have a door that cannot be opened, embedding a magnet can quickly solve it. Just screw the countersunk magnet to the floor at the edge of the door, and then screw another to the door (if it is not magnetic yet). After the door is opened, it will latch on the magnet on the floor and remain intact. You can also use magnetic latches to keep kitchen cabinets or drawers and filing cabinets or storage cabinets closed. Indeed, anything can be opened or closed with a powerful neodymium sink magnet! Hidden magnetic holder Need a place to hide your family’s secret jewelry? Using a photo frame and some countersunk magnets, you can create a hidden compartment for additional storage. First, cut out or find a wooden frame that can fit inside the photo frame. Add a magnetic board behind the frame, and install a magnetic latch between the wooden frame and the photo frame. By adding paintings or pictures to the frame, any content added will remain hidden. You can use tack magnets to hang items. Thank you for reading our article. We, Ningbo Tengxiao Magnetic Industry Co., Ltd, have both countersunk magnets and permanent magnet components, and other products. Welcome to visit our official website.

    Types of Permanent Magnets

    Considering the inherent strength of magnets (relative to mass and weight), magnets can be used in many different applications. Since electromagnets can be turned off and on, they can be used in powerful equipment and vehicles, such as magnetic levitation or magnetic levitation trains. However, permanent magnets are also very versatile and robust components in countless applications. A magnet is any material or substance that projects a magnetic field. A magnetic field is a type of vector field, which aligns the charges on the dipoles. Magnets have both a south pole and a north pole, and they align with the magnetic south and north poles of the earth (and are not fixed points on the map, but are usually located in the changing area of the north and south poles in the geographic area). It's like two poles repel each other, not like two poles attract each other. Ferromagnetic materials (that is, materials that contain a certain amount of iron) can usually be permanently magnetized with a sub-base: if the magnet is heated to a known high temperature, they may lose magnetism. This can be solved by slowly cooling the magnet for remagnetization. Scientists use four basic methods to classify magnets according to how they are used. We list the following categories: 1. The attractive or repulsive force of a magnet. 2. The ability of a magnet to convert electrical energy into mechanical force. 3. The ability of a magnet to convert mechanical force into electrical energy. 4. The ability of the magnet to affect the beam. Ningbo Tengxiao Magnetic Industry Co., Ltd. has products such as permanent magnet components and permanent magnet motor assembly. Please contact us if you need them.
  7. Ningbo Tengxiao Magnetic Industry Co., Ltd. is a professional supplier of magnetic products and magnetic equipment, specializing in the production of high-quality ring neodymium magnets, magnetic badges, magnetic office supplies and other magnetic equipment, as well as custom industrial magnets. Nd-Fe-B magnets are extremely magnetic. Please prevent your hands or other parts of your body from being caught by magnets. For large-scale strong magnetic requirements, more attention is paid to safety. Do not place strong magnets near patients with electronic medical equipment or pacemakers. Do not swallow strong magnets. If swallowed by mistake, seek medical attention immediately. Keep strong magnets out of reach of children. When using a magnet, keep the environment clean to prevent small impurities such as iron filings from being adsorbed on the surface of the magnet and affecting operation. Magnetic debris flying into the eyes may cause damage and must be handled with care. NdFeB magnets should be stored in a dry and ventilated environment. Acidic, alkaline, organic solvents, salt water, high temperature and humid environments will only oxidize the magnet, the coating will fall off, and the magnet will be powdered and demagnetized. After the magnet is heated at high temperature, its magnetic function will be weakened. Please refer to the temperature resistance guidelines for the corresponding functions of the magnet, and pay attention to the temperature not too high during the assembly or operation of the magnet. Nd-Fe-B magnets are fragile, so when they are used in places subject to vibration or shock, they may break or fall. During use, please be careful not to touch it.

    Why are some items magnetic?

    Ningbo Tengxiao Magnetic Industry Co., Ltd. is a professional supplier of magnetic products and magnetic equipment, specializing in the production of high-quality NdFeB magnets, magnetic badges and other magnetic equipment as well as customized magnetic office supplies. Simply put, magnetism means that a substance will be subjected to magnetic force when placed in an uneven magnetic field. In the same inhomogeneous magnetic field, the direction and strength of the magnetic force per unit mass of the material determines the magnetic strength of the material. Because any substance has magnetism, any substance will be subjected to magnetic force in an uneven magnetic field. What really exists in the space around the magnetic poles is not the lines of magnetic force, but a kind of field, which we call a magnetic field. The mutual attraction of magnetic substances, etc. is carried out by the magnetic field. We know that there is universal gravitation between matter, which is a kind of gravitational field. Similar to the magnetic field, it is a field that fills the space around the magnetic pole. The strength of the magnetic field can be represented by the number of imaginary magnetic lines of force, where the magnetic field lines are dense, the magnetic field is strong, and the magnetic field lines are weak. The number of magnetic field lines passing through a unit section is called the magnetic flux density. Moving charged particles are subjected to a force called Lorentz in a magnetic field. The strength of the magnetic field is determined by the magnitude of the Loren magnetic force received by the same charged particle in different magnetic fields. Tesla is the international unit of magnetic flux density. The magnetic flux density is the basic physical quantity describing the magnetic field, and the magnetic field strength is the auxiliary quantity describing the magnetic field. Tesla (Tesla, N) (1886~1943) was a Croatian-American electrical engineer who invented transformers and AC motors. The magnetism of substances is not only universal, but also diverse, and therefore has been widely studied and applied. The matter close to our body and surroundings, as far as the matter in various stars and interstellar bodies, the atoms, nuclei and elementary particles in the microscopic world, and various materials in the macroscopic world all have one or another magnetism.

    How are NdFeB magnets made?

    Ningbo Tengxiao Magnetic Industry Co., Ltd. is a professional supplier of magnetic products and magnetic equipment, specializing in the production of high-quality NdFeB magnets, countersunk magnet and other magnetic equipment. Let me introduce to you NdFeB magnets. Neodymium iron boron magnets, as the name suggests, are mainly composed of neodymium, iron, boron and other raw materials, and then add related raw materials such as copper, aluminum, dysprosium, terbium, etc. according to the design performance requirements, put them into the melting furnace, and smelt into alloy blocks before crushing , The large pieces are broken into small pieces, and the small pieces are broken into fine particles. According to the design performance requirements, equipment such as jet mill or hydrogen breaker will be used. After crushing, it is die-casted into shape, and then put into a sintering furnace for sintering. After the furnace is released, it is processed into all the shapes we currently see: square magnets, disc magnets, ring magnets, tile magnets, triangles, magnetic balls Etc., it is shipped through electro-galvanized or nickel-magnetized packaging. The main components of neodymium iron boron magnets are rare earth (Re), iron (Fe), and boron (B). In order to obtain different properties, rare earth Nd can be replaced by some other rare earth metals such as dysprosium (Dy) and praseodymium (Pr). Iron can also be Cobalt (Co), aluminum (Al) and other metals are partially replaced. The boron content in the neodymium iron boron strong magnet is small, but it plays an important role in the formation of tetragonal crystal structure intermetallic compound. The compound has high saturation magnetization and high The uniaxial anisotropy and high distance temperature. NdFeB magnet production tools: smelting furnace, jaw breaking machine, ball mill, jet mill, compression molding machine, vacuum packaging machine, isostatic press, sintering furnace, heat treatment vacuum furnace, magnetic performance tester, Gauss meter.

  10. Ningbo Tengxiao Magnetic Industry Co., Ltd. is a professional supplier of magnetic products and magnetic equipment. Let me introduce one of our company's products: Pot Magnet. If you are interested in us, please continue reading: Pot-shaped magnets with steel shell Pot-shaped magnets are permanent magnets housed in a steel shell, sometimes called pot-shaped, so they are called "pot-shaped" magnets. Permanent magnets can emit a magnetic field without any electrical energy. Types of pot magnets: bipolar, countersunk, internal thread, stud and through hole pot magnets have five forms: bipolar, countersunk, through hole, internal thread and stud. The special feature of Pot Magnet is the increased adhesion due to the metal pot. The magnetic core is located in it, so the bonding surface remains free. Therefore, the adhesive force acts on one side of the magnet. The pot changes the magnetic flux, thereby increasing the force. Therefore, even relatively small magnets can be adhered very firmly. These magnets are versatile and suitable for commercial and private use. For example, they can be used as gripping magnets for industrial purposes and used to transport steel parts. Therefore, some people say deep pot. Such magnets are also very suitable for fast and fast detachable fasteners without drilling holes. Whether it is used for trade fairs and store construction, or used to assemble magnets in private homes, for hobbies and other purposes. The advantages of pot magnets are strength and durability. Due to the optimized magnetic circuit, the pulling force of the pot magnet is much stronger than that of the magnet of the same size. The steel cup can protect the magnet from direct impact, thus greatly improving the durability. In addition to Pot Magnet, we also produce Badge Magnets.

  11. Magnets that can maintain their magnetism for a long time are called permanent magnets. Such as natural magnets and artificial Magnetic Steel. Permanent magnets are hard magnets, which are not easy to lose magnetism and are not easy to be magnetized. The materials used as magnetic conductors and electromagnets are mostly soft magnets. The polarity of the permanent magnet does not change, while the polarity of the soft magnet changes with the polarity of the applied magnetic field. A permanent magnet is an object that can retain a certain residual magnetization after the external magnetic field is removed. To make the residual magnetization of such an object zero and the magnetism completely eliminated, a reverse magnetic field must be added. The magnitude of the reverse magnetic field required to completely demagnetize the ferromagnetic substance is called the coercivity of the ferromagnetic substance. Both steel and iron are ferromagnetic, but their coercive force is different. Steel has a larger coercive force, while iron has a smaller coercive force. This is because in the steelmaking process, carbon, tungsten, chromium and other elements are added to iron to make carbon steel, tungsten steel, chromium steel, etc. The addition of carbon, tungsten, chromium and other elements causes various inhomogeneities in the steel at room temperature, such as uneven crystal structure, uneven internal stress, and uneven magnetic strength. These uneven physical properties all increase the coercive force of steel. And the greater the degree of unevenness within a certain range, the greater the coercive force. However, these inhomogeneities are not the best state that steel has or has reached under any circumstances. In order to achieve the best state of internal inhomogeneity of steel, proper heat treatment or machining must be carried out. Steel or other materials can become Permanent Magnet Components because after they are properly processed and processed, the internal unevenness is in the best state and the coercive force is the largest.
