1. The problem statement, all variables and given/known data A magnet of mass 0.10 kg is dropped from rest and falls vertically through a 35.0 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 1.50 m/s. How much heat energy is dissipated to the environment? 2. Relevant equations E = mgh 3. The attempt at a solution h = 35 cm --> .35 m E = (.10 kg) * (9.81) * (.35 m) = .3433 J Is the equation incorrect?
