WebThe exact reason for induced EMF is the change in flux linkage with respect to the coil which continues until the movement of both magnet bar or coil is stopped. In other words, a strong magnetic field or flux won’t induce EMF in the static conductor. Hence, change in flux is the must have phenomena to induce EMF either in coil or conductors.
