description Methods and apparatus for characterizing magnetic properties of materials, such as a material's anhysteretic B-H characteristic or its permeability as a function of B or H. A test apparatus for determining these magnetic properties is constructed to yield a symmetrical field distribution through material being tested to avoid localized saturation within the material. Characterization methods take into account radial variations in tangential field intensities when calculating the magnetic properties. The calculations are obtained as solutions of optimization problems through optimization methods such as genetic algorithms.
