Question

Two identical loops one of cu and al are rotatedwith same angular speed in the same magnetic field compre induced emf

Answer 1

it answer is" cu "

as it's specific resistance is low than "al "

so more eng is produced by copper

Answer 2

Hi mate here is ur query..

============

* 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

Induced emf (V) = -∂Φ/∂t

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

Φ = ∫B⋅dS (dot product)

#So, we can say that 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.

============

Hope this will help you..

Good luck!!!!
