what are Closed Circuit Condition and Open Circuit Condition
A magnetic circuit is made up of one or more permanent magnets or/and electric current carrying conductor, and generally some high permeabil...
What are the Basic Features of the Magnetic Flux?
We have discussed that magnetic flux is a contrived but measurable concept that has evolved in an attempt to describe the “flow” of a magnet...
How about the Surface Protection?
Sintered Nd-Fe-B magnets are relatively inferior on corrosion resistance comparing with the traditional magnets such as Sm-Co, Alnico and fe...
What is the Fabricating Process routine of Sintered Nd-Fe-B
The sintered Nd-Fe-B magnets are usually formed by powder metallurgical processes. The general fabricating process routine is as follow:· Me...
What is Nd-Fe-B Permanent Magnets?
Nd-Fe-B (neodymium-iron-boron) material was discovered in 1983 by physicists of United States and Japan. It is the strongest man-made perman...
How to Determine the Demagnetizing Factor and the Operating
Self-demagnetizing field is the only magnetic field exists within a permanent magnet when there is no external field. Thus, it is the origin...
