Question

The magnetic flux linked with the coil changes to 4*10-2W when the current changes by 0.02A. The self-inductance of the coil is

Answer 1

Answer:

4×10=40

Answer 2

Faraday's Principle of Electromagnetic Induction states that the emf induced in a loop due by a changing magnetic flux is equal to the rate of change of the magnetic flux threading the loop. The magnetic flux threading a coil of wire can be changed by moving a bar magnet in and out of the coil.
