In order to induce a voltage in a coil of wire, the magnetic field must be changing. E=N*area*dB/dt where area is the area of the coild and B is flux density. Either the coil must be moving or the magnetic field must be changing.

The current flow is due to voltage generated for which the magnetic flux must change.
