I want to know that How can I measure the magnetic flux density in HFSS? I have a box in my model that I defined as a magnetic media, I want to measure the magnetic flux density that is generate because of this particle. I know I can get the magnetic field strength Mag_H_field , but I want to know the B (magnetic flux density)
@Najme;as you know the relation between B and H is B=uH.and u=u0*ur.Their is not big difference between B and H but if you want to know get the data sheet of result output of H and divide with the relative permeability of material and u0, but you will not get 3d value. The individual value you can put in excel to get the plot
There is a big difference between B and H. B can be in a different direction to H inside a permanent magnet, or any magnetic material which has hysteresis.
In SI units uo is nearly 4 pi e-7, and ur can be from 1 to thousands depending on the material.
I don't know HFSS but you may be able to post-process by multiplying H by the magnetic properties of each material and so get B, which HFSS may plot for you, or give you values you can use.
