Amagnet of mass 0.10 kg is dropped from rest and falls vertically through a 25.0
Amagnet of mass 0.10 kg is dropped from rest and falls vertically through a 25.0 cm copper tube. eddy currents are induced, causing the copper to warm up. the speed of the magnet as it emerges from the tube is 1.40 m/s. how much heat energy is dissipated to the environment?
