In order to produce an electric current in a coil of wire, a magnet field through the coil must be moving.
Electromagnetic induction is a process in which electric field is produced due to the change in the value of magnetic field.
So, for the production of an electric current in a coil of wire, a magnet field should be moving through the coil of wire. Process of this electromegnetism get clear through the below attached image.
Hence magnetic field should be moving.
