Solve by difficulty
A small circular loop of wire of radius a is located at the center of a much larger circular wire loop of radius b. The two loops are in the same plane. The outer loop of radius b carries an alternating current I=Io cos (ωt). The emf induced in the smaller inner loop is nearly :

Induced Electric field
Whenever a magnetic field is varying with time, an induced electric field is produced in any closed path, whether in the matter
or in empty space. This Induced electric field is directly proportional to induced emf as .
And this is given as
This is known as an integral form of Faraday’s laws of EMI.
Properties of Induced electric field-
- The induced electric field is different from the electrostatic field. As it is non-conservative and non-electrostatic in nature.
- Its field lines are concentric circular closed curves.
- This field is not created by source charges.
- Its direction is along the tangent to its field lines.
