A magnet of mass 0.062 kg falls through an aluminium tube 0.95 m long. It moves at a steady speed of 0.069 m/s all the way. How much heat do the eddy currents make in the tube during the passage? Take g = 9.8 m/s².

← The sheets of a transformer core are 220 µm thick. The core is rebuilt with sheets of 110 µm and run at twice the frequency. At the same time the peak field is cut to one third. By what factor does the eddy-current loss in each cubic metre change?
A long wire is wound into a solenoid of length l and radius r, with evenly spaced turns. Its inductance is L. The same wire is wound again into a solenoid of the same length l, with evenly spaced turns, on a former of half the radius. What is the new inductance? →
