The determination of the hysteresis curve for thick tape cores

Probably the most common problem that arises when using magnetic materials concerns the prediction of the flux-time curve, for a particular core, given the current-time curve, or vice versa. Quite often, the magnetization is a periodic function of time, even in the case of the ¿d-c loop,¿ so that the ¿-I curve is a closed loop. Therefore, it can be said that the original problem is to find the ¿-I loop for the above conditions.
