## Eddy Currents

The rectangular coil used so far is made of a rectangular frame and an empty internal space. Let's replace it with a solid rectangular plate, as shown in the figure below.

Again, the moving force F (here due right) encounters an opposition by the magnetic force Fm in the opposite direction. However, the induced current does not flow in a single direction and only in the lateral frame as in the case of rectangular frame discussed earlier, rather, electrons swirl around in circular paths as shown in the figure. The currents produced due to this phenomenon are known as eddy currents (eddy = whirlpool).

Again, in this case, the current induced in the plate generates an induced emf and therefore, it produces some energy dissipated in the form of heat.
