Abstract :
A new method of measuring reversible permeability is described. The method is not limited by the need to employ laminated specimens of material, since allowance is made for eddy-current effects within the specimen. Measurements were made on solid-bar specimens of two types of rail steel at a frequency of 5 kHz. The results cover biasing field strengths between 160 and 170kA/m.
