The transverse distribution of induced eddy currents across a flat conducting strip of finite width, due to a rectangular d.c. magnet moving above it, has been modelled experimentally, and has been compared with that calculated for an infinite sheet. The electrodynamic suspension was simulated by means of a stationary a.c.-excited copper magnet suspended above an aluminum strip, and the induced surface current density was measured by a voltage pickup probe connected to a look-in amplifier.
