two loops one of copper and other of aluminium are placed in same external fields and rotated about diameter..compare emf induced and current in the loops.

Emf induced will be same in both loops.

Current induced will be more in Copper loop as Conductivity of copper is more than aluminium.

 yes,,,,I don't have exact idea which has higher conductivity copper or Al,,,,but that one which has Higher Conductivity,,will carry higher current ...........

 

Second EMF will be constant because it depend on the flux change not on the material.
