question1: In the calculation of magnetic field , I have a expression of B-H curve, is B=B(H). Then in the "Ampere's Law", When constitutive relation is "B=mu0*(H+M)", what shoud be filled in the magnetization intensity M? If it is M(H), I can get it from "M=B(H)/mu0-H". How do I write the M(H)? If not, what should I write?
question2: In transient calculation, I have three B-H curves, are B1(H), B2(H) B3(H), and have three i-t curves, are i1(t), i2(t) i3(t), and they are corresponded. When exciting current is i1(t), the B-H curve used is B1(H); When exciting current is i2(t), the B-H curve used is B2(H);When exciting current is i3(t), the B-H curve used is B3(H). it makes different current is corresponded with different B-H curve. In comsol 4.3b, how I achieve it？
thank you
