Question

The direction of induced e.m.f. during electromagnetic induction is given by 

Moderate
Solution

Lenz’s law is used for determining the direction of induced current.

Lenz’s law of electromagnetic induction states that the direction of induced current in a given magnetic field is such that it opposes the induced change by changing the magnetic field.

The direction of induced e.m.f. during electromagnetic induction is given by

(a) Faraday's law

(b) Lenz's law

(c) Maxwell's law

(d) Ampere's law
