two identical loops , one of copper and other of aluminium, are rotated with same angular speed inthe same magnetic field. compare 1) the induced emf and 2) the current produced in two coils. justify your answer.

Induced emf will be same in the both but Induced Current will be more in Copper loop.

As The voltage induced in each turn is

V = -∂Φ/∂t


Φ = total magnetic flux through the coil (Wb).


Φ = ∫B⋅dS (dot product)

so, As the rate of change of magnetic flux will be same for both the coils, thus the induced emf will also be same as it does not depend on the material of the coil. But induced current will depend on the material of coil.
