Abstract :
A method of calculating eddy-current impedances for giant magnetostrictive materials during dynamic magnetization is suggested. The method is based on solving the power-balance equation for each time step of the recorded data. The experimentally obtained impedances can be used for accurately modeling the magnetostrictive process
