Effective magnetic parameters in the presence of hysteresis

Hysteresis-based effective parameters ([l.sub.eHys] and [A.sub.eHys]) are described that are extracted from minor and major loop measurements, and are thus more suitable for computations involving these loops. For three commercial power ferrites, formulae are given for [l.sub.eHys] and [A.sub.eHys] of toroids with radius ratio [k.sub.r] between 0.2 and unity.
