Solution

Verified by Toppr

The correct option is E All of the methods listed can be used to induce current into a coil of wire
Faraday's law of electromagnetic induction states that when the magnetic flux linked with a coil changes , an emf is induced in it.
It is clear that in all given methods , magnetic flux linked with coil is changing , therefore voltage will induce in coil by all the given methods.
