The service life of NdFeB
Small disc neodymium magnets The stability of permanent magnetic material performance is an important indicator of permanent magnetic materials. Stability mainly refers to the process of magnetic properties changing under the influence of internal and external factors after magnetization, and is usually expressed by the rate of change of performance indicators small disc neodymium magnets. […]

Shape Anisotropy, Demagnetization Field and Demagnetization Factor of Permanent Magnets
A disk neodymium magnet The permanent magnet is made into a certain shape. For example, if the magnetization curve in the open circuit state is measured along the x, y, and z directions of the Disk Neodymium Magnet, it can be found that along the x direction, only a lower magnetic field (H1) is needed […]
What is the Difference Between a Single Pole Neodymium Magnet and a Regular Neodymium Magnet?
Neodymium magnets have revolutionized various industries due to their exceptional strength. Made from a unique alloy of neodymium, iron, and boron (NdFeB), these permanent magnets pack a powerful punch in a compact size. But what if you could harness this strength in a magnet with only one magnetic pole? Enter the concept of the single […]

What is a magnetic domain?
Electro Permanent Magnet According to the characteristics of the material in the external magnetic field, the material can be divided into five categories: paramagnetic material, diamagnetic material, ferromagnetic material, ferrimagnetic material and antiferromagnetic material. Ferromagnetic material electro permanent magnet is a material that can maintain its magnetized state even if the external magnetic field disappears […]
Magnetic Couplings
Permanent Magnet Material Permanent magnetic couplings are a new type of coupling that connects the prime mover and the working machine through the magnetic force of permanent magnets. It does not require direct mechanical connection, but uses the magnetic coupling between permanent magnets. The magnetic field can penetrate a certain spatial distance and the characteristics […]
