Question

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
(ii) the current produced in the two coils justify your answer.


Solution

Solution (i) There will be no difference in
the induced emf because induced
emf is dependent only upon the 
magnetic field and angular vel but 
not on the property of metal in loops  
(ii) The induced current will be 
higher in copper loop since the 
resistance of Aluminium is greater 
then of copper and the induced emf
is same in both.
