Powerful magnet hardness strong magnet hardness hard: powerful magnet density of the added rare element, make a magnet than ordinary magnet for hard a lot.
When use did not avoid collisions, will not affect the integrity of the magnet.
While magnet for fragile can't keep the appearance for a long time.
Market in children's hand tool based on how many COINS as the standard, and a strong magnet is its magnetic force several times and even hundreds times.
Powerful magnet magnetic force strong, general installation these powerful magnet of the workers have to be careful, avoid to cause injuries, visible how strong the magnetic force.
Permanent magnet materials usually have larger negative magnetic temperature coefficient & alpha;
B, following the increase of temperature, the residual magnetism br will reduce, showed that poor thermal stability of the permanent magnet.
Therefore, request of magnetic steel & alpha;
B, the lower the better, had better be & alpha;
B close to zero.
Ndfeb magnet & alpha;
B minus zero percent.
Than drill and rare earth aluminum nickel samarium cobalt magnet steel, only smaller than ferrite.
The ferrite & alpha;
B minus zero percent.
Can be applied in 200 degrees Celsius, due to the intrinsic coercive force of ferrite am is positive temperature coefficient, flux under the positive temperature change is reversible;
The ndfeb have larger negative & alpha;
M, minus zero percent.
