Permanent magnets, the kind found on refrigerators everywhere, exist because their constituent atoms behave as miniature magnets. They align and combine to form the larger magnet in a phenomenon called ferromagnetism. There are so…
Nearly every neodymium magnet will be plated or coated and, as the most powerful permanent magnet available, they are used in many different applications. However, they possess physical characteristics that require them to be plat…
NdFeB magnet is a kind of magnetic material with high remanence, high energy product and high coercivity, also known as magnetic king. Because of its high value for cost, it is widely used in various fields. However, Neodymium mag…
Permanent magnets Permanent magnets are ‘hard’ magnetic materials, i.e., materials that, once magnetized, retain their magnetization at the temperature of use. Their magnetic properties are primarily determined by the properties o…
The term “Curie temperature (Tc)” or “Curie point” gets frequently mentioned when discussing magnets and magnetic properties. The Curie temperature relates to the maximum temperature a material can reach before losing its magnetic…
Permanent magnet motors using neodymium iron boron magnets as motor magnets have small size, light weight, high torque-inertia ratio, high servo system response, high power and speed/weight ratio, high starting torque, and energy …
