| 1.Magnetic Field: the space that
can produce magnetic force to magnetic pole.
2.Magnetic Field Intensity:
(H) magnetic field electrical which was produced by electrical
gyroidal winding.Namely,if the unitage length of electrical
gyroidal winding is ¡°n¡± and the passing electric current is
¡°I(A)¡± then H=I*n.
3.Flux Density (B): the product
of vacuum magnetoconductivity (¦Ì)and intensity of magnetic
B=¦Ì*H
4.Flux: flux density of unitage
area ¡Ó=B*S(¡°S¡± is unitage area)
5.Max Energy Product (BH(max)):
smallest volume exists most large magnetic power.
6.Coercive Force (Hcb): magnetic
field intensity which realize to change the magnetic direction
opposite to earlier direction.Namely, if the process is controlled
by remove magnetic domain then the power that resist this
process called Coercive Force.
7.Residual .Flux Density(Br):
magnetic induction intensity(Flux Density) when saturated
magnet (including magnetic field which demagnetized by itself)decrease
monotonously according to saturated hysteresis curves to zero.
8.Sreface Magnetic Field: appointed
palce on permanent magnet.
9.Anisotropic magnet:different
crystal has easy or difficult magnetic direction characteristic
it attribute to the direction of crystal component.
