Paramagnet / Diamagnet

Please login with a confirmed email address before reporting spam

Dear Community,

i am a student and i want to study the behavior of a paramagnetic solid in a magnetic field induced by a single coil with a current passing through which i modeled.

Is there a possibility to calculate the force acting on the solid by the magnetic field?

Thanks for the help.

Hi

check the doc, I do not see why you should not be able apply either the Maxwell stress tensor approach (note its rather sensitive to mesh density and field gradients) or better the virtual work approach, somewhat more cumbersome to set up. There are several exaples in 3.5a, not sure all are already translated to V4.0a yet

Good luck
