Causes of Degauss of Nd-Fe-B at normal temperature

When the NdFeB magnetic material is severely impacted, it may be degauss. Why is this? Because the NdFeB magnet will be subjected to violent external force when it is hit, it may cause changes in its internal structure. Does not show magnetism to the outside... ...More>>

How to observe magnetic domains?

Magnetic domain observation methods can be roughly divided into the following three types:1) Scanning Electron Microscope (SEM) 2) Scanning Probe Microscopy (SPM) 3) Magneto-optical Kerr effect microscope... ...More>>

What size is 2000 gauss neodymium magnet?

Whether it is a 1000 gauss, 2000gs or 3000gs magnet, they do not have a fixed size, because the gauss value of the magnet is related to the material, performance level, size, thickness, etc. of the magnet, and there is no such thing as a 2000gs permanent magnet. a standard value.... ...More>>

What does the intrinsic coercivity(Hcj) of a magnet do?

Different from the coercive force, when the reverse magnetic field H = Bc, although the magnetic induction intensity B of the magnet is 0, the magnet does not show magnetic flux to the outside, but the vector sum of the microscopic magnetic dipole moments inside the magnet is often not 0, and also That is to say, at this time, the magnetic polarization of the magnet tends to maintain a large value in the original direction.... ...More>>

Can the size of arc magnet be customized ?

Arc magnets are often used in the rotor or stator of DC motors. Due to the different motor models, revolutions, working environment, etc., the material and size of the magnets are also different, so it involves customization. Generally, magnet manufacturers can For non-standard customization, you only need to provide drawings and some detailed parameters.... ...More>>
