A popular demonstration of eddy currents is to drop a magnet down a long metal tube and a long glass or plastic tube.As the magnet falls down the tube there is changing flux as the magnet falls toward or away from each part of the tube.What tube has the larger voltage induced in it and what one has the larger current induced in it. V I
A)metal metal
B)glass glass
C)glass metal
D)same metal
E)same same

Question
