## Main Question or Discussion Point

the idea is , if we have the magnetic field strength (H) and magnetic flux density (B) so we represent the 'hysteresis cycle' to be B(H)=B my question is could we deduce mathematically the hysteresis curve ?? for example if we can provide a model of a nonlinear ODE so

[tex] \frac{dB}{dH}= B^{r}- (1/B) [/tex]

or something similar, i would be interested in the differential equation satisfied by B=B(H) thanks.
