Two identical loops, one of copper and the other of aluminium, are rotated with the same angular speed in the same magnetic field. Compare (i) the induced emf and (ii) the current produced in the two coils. Justify your answer.
As B, A, w are same for both loops so induced emf is same for both loops.
(ii) Current induced I = ε/R
As resistance R is less for copper loop, so current induced is larger in copper loop.
