1.	In which of the following cases does the electromagnetic induction occur? i) A current is started in a wire held near a loop of wire. ii) The current is stopped in a wire held near a loop of wire. iii) A magnet is moved through a loop of wire. iv) A loop of wire is held near a magnet.
Answer» In first three cases there is a change in magnetic flux. So electromagnetic induction occurs in first three cases
