Abstract

Eddy current magnetization of spherical and cylindrical samples of technical copper and aluminum were measured in a pulsed field magnetometer using different pulse durations. The magnet was subdivided into two sections with two layers, to allow a variation of the time constant of the system. Axial-symmetric problems in electrodynamics were solved using a finite element program. Good agreement was found between the measured eddy-current moment as a function of the applied field with that calculated by a finite element program.
