rial, the relative permeability of this inductor ranges between 50 and 20000. The domain structure of this material responds when a magnetic field is applied; without a magnetic field, the or entation is random. Core losses are generated when the magnetic energy cha
Thus, larger inductors require lower effective core permeabilities (or relatively larger air gaps). Only two situations would raise the optimum effective permeability: an operating core flux density higher than 2000 gauss, or an inductor significantly smaller than a 30/19 pot core.
