C is the Magnetization reversibility , I guess it should not affect the inductance but I think A will affect when I tried altering the A value higher and lower the inductance varies towards the saturation. So hope its fine
But just wanna how did he get these values , I get these values auto generated by the jiles atherton model from the B-H curve points
Did he use some other model or the range is much higher/lower than what I gave or is it something else , just curious?
