magnetic conductivity การใช้

Magnetic conductivity non - magnetic alloy with very high strength , excellent wear resistance and very low magnetic conductivity , used for forming ddie for permanent - magnetic materials
Based on it the electromagnetic response under different depths of the 3 dimensional geologic body with different resistivities , magnetic conductivities and dielectric constants is simulated
The paper proves that in the 2d non - linear case , the coulomb gauge is been meet naturally . in the paper , the second - order isoparametric fem is adopted in the non - linear transient magnetic field simulating excited by current source and the results of transient field and static field solved by the second - order isoparametric and linear fem are compared and analyzed , besides , the effect of the eddy currents in the magnetic materials of the different conductivity is analyzed , it is obtained that the magnetic material of high magnetic conductivity and low loss should be chosen in designing of pma
