Hello everyone. I'm working on a project where I have to do a finite element simulation of low frequency magnetic coupling. But my problem is that I don't know the permeability of all the objects involved. Can anyone suggest a good way to measure the permeability of these objects ? The objects are quite irregularly shaped, i.e. not spheres or boxes or cylinders. I have one idea myself. I could make a coil of sufficient size and then put the object inside this coil, and measure the inductance. Then I could set up an identical finite element simulation and then adjust the permeability of the object until I get the same results as in the measurement.
