Understanding Magnetic Permeance Coefficient

Firstly, it is important to understand that the maximum working temperature of a NdFeB magnet is not defined by the material grade! It is essential to calculate the magnetic permeance coefficient to establish what grade of material you need. The two examples compare the same magnet but with different thicknesses, one at 30mm and one at…

Coatings for Neodymium Magnets

Coatings for Neodymium Magnets

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 plated or coated in order to protect them from damage. In their raw form, neodymium magnets are quite brittle, and as…

The History of Neodymium Magnets

History of Neodymium Magnets banner

The origin of the neodymium magnets dates back to 1885 when Carl Auer von Welsbach, an Austrian scientist and inventor, separated didymium into the new separate elements neodidymium (“new didymium”) and praseodidymium (“green didymium”).  In time, the element names would change to neodymium and praseodymium. Neodymium (Nd) is the fourth member of the lanthanide ‘rare-earth…
