Question

In the demonstrations of eddy current, it involve s non-conservation of mechanical energy. such as: (1) large magnet slowing down to a stop at the end of a short drop, before hitting the copper plate (loss of kinetic energy), (2) a magnet moving downward at a constant velocity (loss of potential energy), or (3) a pendulum slowing down to a stop (loss of total mechanical energy). These mechanical energies are likely being lost to heat; explain the mechanism by which this loss happens. [Hint: What happens when a current flows in a material with non-zero resistance?]
