Hi guys

 

I am really, really struggling to find the full saturated B-H curves for different ferromagnetic materials. So far the only data I have been able to find is third quadrant magnetization curves or normal (virgin) magnetization curves. Looking for something in an excel table, but I can also make due with pics if that is the only option. The reason I need this is to match a hysteresis simulation to some measured results.

Hi CasualKilla, what you seek is called a "demagnetization curve", where you see the hysteresis, and materials supppliers use to provide them, generally as a picture. But you have to look for each material individually.

 

If your material is not meant for EM uses, it gets more difficult.

 

I have some from Metglas, Thyssen Krupp, Vacuumschmelze - that is, unusual materials.
