Solution
The correct option is C magnetic flux
When there is a change in the magnetic flux interacting with the wire, a current is induced in the wire. Hence, when a magnet is brought close to a wire or taken away from a wire, a current is induced as the magnetic flux interacting with the wire changes. When a magnet is kept close to a wire or kept far from a wire, the number of field lines interacting will be constant. Hence, no current is induced in the wire.
