Abstract :
An analytical approximation for the relative incremental permeability of soft ferrites as a function of the magnetic field H is proposed. The numerical values of the parameters of the approximation are given for several current materials. Experiments confirming its validity are reported. The approximation is useful in design of nonlinear magnetic components and in analysis of circuits using them
