I'm interested in modelling Hysteresis Curve for Permanent magnet using Preisach Model. I have tested the magnet for its magnetic properties like Remenance, Coercivity, Intrinsic Coercivity and Max. Energy Product (Br, Hc, iHc& BHmax). Kindly share your thoughts so I could able to create a model using analytical formula or is there any software where I can use the same.
