B. Moving a magnet up and down near the wire.

Electric current can be induced by a changing flux of the magnetic fields passing through the wire. This is the phenomenon of electromagnetic induction, in which, an electromotive force is introduced across a conductor exposed to time varying magnetic fields. In this case, wire is the conductor and varying magnetic field is provided by moving up and down of magnet near the wire.
