Hi,
does anyone know a model in COMSOL, which shows the dependence of the magnetic field with the temperature of pole shoe?
Thanks for answers
Markus

Hi

I do not know of any, but for me that is obtained easiest by modifying the material properties of your magnet and add a T dependence, as most materials are defined with rho(T), Cp(T), eta(T) .... so why not with a magnetisation that has its "T" dependence.

note: you make your model non linear like that it will have more trouble, and/or need more time, to solve

Good luck
