Can NdFeB Absorb Objects 600 Times Its Own Weight? Not Exactly

Can NdFeB Absorb Objects 600 Times Its Own Weight? Not Exactly Magnets can pick up heavy objects. It is said on the Internet that NdFeB magnets can pick up objects 600 times their own weight. Is this accurate? Is there a formula for calculating magnet attraction? Today, I will tell you about the "attractive force" [...]

  • Radiation Ring Magnet

Radiation Ring Magnet

Radiation Ring Magnet Sintered NdFeB magnetic ring is a new product developed in recent years. It is mainly used in high-performance permanent magnet motors and sensors. In the application of permanent magnet motors, sintered NdFeB magnetic tiles are usually bonded into a ring, which has natural disadvantages: Since the processing of the tile-shaped magnet belongs [...]

  • Eddy Current Loss of Rare Earth Permanent Magnet

Eddy Current Loss of Rare Earth Permanent Magnet

Eddy Current Loss of Rare Earth Permanent Magnet Both samarium cobalt and neodymium iron boron are metal materials. Due to the good electrical conductivity of metal materials, the resistivity is very low. This is not a good thing for rotating machinery such as motors, because it will bring eddy currents to rotating machinery Loss, causing [...]

  • Magnetic Materials in Voice Coil Motors (VCM)

Magnetic Materials in Voice Coil Motors (VCM)

Magnetic Materials in Voice Coil Motors (VCM) Voice coil motor, VCM is a special form of direct drive motor, which can directly convert electrical energy into linear motion mechanical energy. The principle is to put a cylindrical winding in a uniform air gap magnetic field, and the winding generates a magnetic field. , Drive the [...]

Sintered NdFeB Weight Loss Test (HAST, PCT)

Sintered NdFeB Weight Loss Test (HAST, PCT) Sintered NdFeB permanent magnets are the magnetic materials with the highest magnetic properties discovered so far, and are widely used in wind power generation, new energy vehicles, maglev trains, intelligent robots and other fields. Sintered NdFeB magnet adopts powder metallurgy process, and the raw materials contain highly active [...]

  • Magnetic Materials in Linear Motors

Magnetic Materials in Linear Motors

Magnetic Materials in Linear Motors Linear motor is a kind of transmission device that directly converts electrical energy into linear motion mechanical energy without any intermediate conversion. It can be regarded as a rotating motor that is radially dissected into a plane (that is, a rotating motor is flattened, and works the same). Linear motors [...]

  • FeCrCo - Iron Chromium Cobalt Permanent Magnet Material

FeCrCo – Iron Chromium Cobalt Permanent Magnet Material

FeCrCo - Iron Chromium Cobalt Permanent Magnet Material The iron-chromium-cobalt permanent magnet material appeared in the early 1970s. It belongs to the age-hardening deformable permanent magnet material. Its alloy composition range is very wide. The basic composition is 20-33% Cr, 3-25% Co, and the rest is Fe. The magnetic performance of FeCrCo is equivalent to [...]

Magnetic Material in Magnetic Separator Equipment

Magnetic Material in Magnetic Separator Equipment The magnetic separator uses the magnetic difference between minerals for separation, which can improve the grade of ore, purify solid and liquid materials, and recycle waste. It is one of the most widely used and highly versatile models in the industry. one. Magnetic separators are widely used in mining, [...]

Halbach Array

Halbach Array, Halbach permanent magnet is a magnet structure. In 1979, American scholar Klaus Halbach discovered this special permanent magnet structure when he was doing electron acceleration experiments and gradually improved it, eventually forming the "Halbach" magnet. It is an almost ideal structure in engineering. It uses special magnet arrangement to enhance the field strength [...]

  • Surface Magnetism

Surface Magnetism

Surface magnetism refers to the magnetic induction intensity at a certain point on the surface of the magnet, and the unit is Gauss Gs or Tesla T (1T=10000Gs). The surface magnetism at different positions on the surface of the magnet is not the same. Generally speaking, "surface magnetism" refers to the center surface magnetism of [...]

  • If Magnet Keeps Doing External Work, Will Its Magnetism Become Weaker

If Magnet Keeps Doing External Work, Will Its Magnetism Become Weaker?

If Magnet Keeps Doing External Work, Will Its Magnetism Become Weaker? The problem itself is actually a misunderstanding of magnets. Magnets can do work, but they do not consume their own magnetism in the process of doing work. Magnets look magical, but they are actually not mysterious. The principle is very similar to that of [...]
