.... Such steels would tend to heat dramatically in the magnetic field were it not for the fact that they are in the form of a laminated structure. By this means, the eddy-current paths are minimized to keep losses low. The thickness of the individual laminations should be held to a minimum. Generally, below 3 kHz...
