To induce an e.m.f. in a coil, the magnetic flux

To induce an e.m.f. in a coil, the linking magnetic flux

Fill in the blank spaces: Emf is induced in a closed coil only when the magnetic flux linked with the coil ___________ with respect to time.

The formula for induced e.m.f. in a coil due to change in magnetic flux through the coil is (here A = area of the coil, B = magnetic field)
