Physical properties of magnets

1. A magnet has magnetism, which is its most obvious characteristic.The Application of Neodymium Iron Boron Magnets in Speakers2. A magnet can attract iron nails in a magnetic field because its molecular arrangement is opposite to the direction of current flow.When a wire passes through the center (or poles) of a magnet, an induced electromotive force is generated.When two mutually repelling objects come close to a certain extent, relative motion occurs between them.5. The compass can be used to determine direction and distance. The working principle of a compass is to deflect the pointer based on the force of the geomagnetic field on the current6. An alternating electromagnetic field is generated in an energized solenoid, which can cut and vibrate metal to produce sound. (Electromagnetism phenomenon: The phenomenon of a changing magnetic field around a conductor that causes a voltage difference between the two ends of the conductor due to the action of Lorentz force.)7. The Earth is a

Will the magnetism of neodymium iron boron magnets disappear?

Will the magnetism of neodymium iron boron magnets disappear? For all magnetic materials, they do not have magnetism at any temperature. Generally, magnetic materials have a critical temperature Tc. Above this temperature, the arrangement of atomic magnetic moments is disordered due to the violent Thermal motion of atoms at high temperature. Below this temperature, the atomic magnetic moments are arranged in order to produce Spontaneous magnetization, and the object becomes ferromagnetic.How can the magnetism of neodymium iron boron magnets disappear? By utilizing this feature, many control components have been developed. For example, the rice cooker we use takes advantage of the Curie temperature of magnetic materials. A neodymium iron boron magnet and a magnetic material with a Curie temperature of 105 degrees are installed at the bottom center of the rice cooker. When the water in the pot dries, the temperature of the food will rise from 100 degrees. When the temperature reaches abo

How is a magnet produced

Ferromagnetic materials such as iron, cobalt, nickel or ferrite are different. The internal electronic spins can be spontaneously arranged in a small range to form a Spontaneous magnetization region, which is called a magnetic domain. After magnetization of ferromagnetic materials, the internal magnetic domains are arranged neatly and in a consistent direction, strengthening the magnetism and forming a magnet. The process of attracting iron by a magnet is the magnetization process of the iron block. The magnetized iron block and the magnet generate attraction between different polarities, and the iron block firmly "sticks" to the magnet.Natural magnets are made of iron trioxide, while artificial magnets are usually made of steel. After being magnetized, steel will always retain its magnetism. Generally, natural permanent magnets are not only ferrite (ferric oxide), but also various permanent magnet materials such as iron cobalt nickel alloys and rare earth alloys of iron, such as alumi

Using different types of magnets

1. Neodymium iron boron permanent magnet is a modern permanent magnet with strong magnetism, and its application range is also very wide.It is mainly used in fields such as electroacoustics, permanent magnet rotors, communication, automotive electronics, magnetic machinery, aerospace, computers, household appliances, medical equipment, office automation, toys, packaging boxes, leather products, magnetic accessories, etc.2. Permanent magnet ferrite is used as a permanent magnet in electricity meters, generators, telephones, speakers, televisions, and microwave equipment. They are also used in various instrument recorders, pickups, speakers, and magnetic cores. They are used for radar, communication, navigation, telemetry, and other electronic devices.3. Samarium cobalt magnets can operate at temperatures up to 300 degrees Celsius and have corrosion resistance and oxidation resistance. They have been widely used in detectors, generators, radars, instruments and other Exact sciences and t

Complete Collection of Weight Calculation Methods for Square, Circular, and Circular Rings of Neodymium Iron Boron

For friends who work in a neodymium iron boron magnet manufacturer, the price of the magnet is calculated every day. When calculating the price, the weight of each shape of neodymium iron boron must be calculated. However, for those who are not professionals, calculating the weight of each shape is quite difficult. The following editor provides common weight calculation formulas for several neodymium iron boron magnet shapes for your reference, hoping to be helpful to you.Square neodymium iron boron1、 Square neodymium iron boron weightCalculation method: Volume * Density=Length * Width * Height * Density/1000, the unit of calculation is g, which is the weight of a single product. If the total weight is calculated, the result can be directly multiplied by the quantity.Example: Square neodymium iron boron size F25 * 10 * 2mm, calculated weight: 25 * 10 * 2 * 7.5/1000 ≈ 3.75g.2、 Formula for calculating the weight of neodymium iron boron discsCalculation method: Volume * Density/1000=Botto

Different types of magnets have different uses.

Magnet classification:Shape magnets: square magnets, arc magnets, irregular magnets, cylindrical magnets, circular magnets, circular magnets, bar magnets, magnetic frame magnets.Attribute magnets: SmCo magnets, NdFeB magnets, ferrite magnets, AlNiCo magnets, Fe Cr Co magnets;Industrial magnets: magnetic parts, motor magnets, rubber magnets, plastic magnets, etc.Magnets are divided into permanent magnets and soft magnets. The permanent magnet plus the strong magnet makes the spin of the magnetic material and the Angular momentum of the electron align in a fixed direction. Apply power to the soft magnet. This is also a way to increase magnetic force. If the current disappears, soft iron will gradually lose its magnetism.
