Effective magnetization and forces due to eddy currents

A simple technique to evaluate the effective magnetization due to eddy currents excited by ac magnetic fields in finite conductive objects is presented. The principal technique relies on assuming a similarity between eddy current magnetization and the magnetization due to diamagnetic effects, which is easier to evaluate. The validity of this method is checked by comparing results regarding the eddy current forces with data acquired from conventional but much more complicated methods or from experimental data.
