Induced electric field is non-conservative and non-electrostatic in nature. Its field lines are concentric circular closed curves.
A time-varying magnetic field dB/dt always produced induced electric field in all space surrounding it.
Induced electric field (Ein) is directly proportional to induced emf, so
A uniform but time-varying magnetic field B(t) exists in a circular region of radius ‘a’ and is directed into the plane of the paper as shown in Fig. 3. The magnitude of the induced electric field (Ein) at point P lies at a distance r from the center of the circular region is calculated as follows:
