Ferrite arc magnet, a kind of arc segmented magnet mainly used in permanent magnet DC motors, according to the motor power and size, the performance and size of arc ceramic magnets are also different, and the grades are mainly Y30, Y30BH , Y35, C5, C8 are the main ones. Today we will introduce the function and application scope of the ferrite arc-shaped bending magnet in the motor.... ...More>>
Main difference between N50 and N52 is the remanence? The N50 remanence range is 1.40T-1.45T, and the N52 remanence range is 1.43T-1.48T... ...More>>
What is the black thing on the outside of the bonded neodymium magnet? What kind of coating is it? In addition, which protective layers can be plated? What is the maximum working temperature for bonded neodymium magnets? Today we will discuss these question.... ...More>>
Radial magnetization permanent magnet is mainly because its magnetization method is radial, and the maximum magnetic force surface is on the side. The reason why radial magnetization is used is to meet the needs of different customers. The following is an introduction to the shape and function of radial magnetization permanent magnets.... ...More>>
Does the magnet have radial and axial magnetization? Yes, I only played magnets when I was young, but I didn't pay too much attention, so radial magnetization and axial magnetization were the first time I heard about it.... ...More>>
Such as mobile phone color screen, camera, vibration motor, circuit board, processor and so on need to use rare earth elements, it can be said that without rare earth, there is no current Apple iPhone.... ...More>>
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>>
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>>
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>>
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>>
