Q. Which law/rule states that the magnitude of the induced e.m.f. is directly proportional to the rate of change of flux linkage?
Solution:
Faraday?s law states that a current will be induced in a conductor which is exposed to a changing magnetic field. Lenz?s law of electromagnetic induction states that the direction of this induced current will be such that the magnetic field created by the induced current opposes the initial changing magnetic field which produced it. The direction of this current flow can be determined using Fleming?s right-hand rule.
Faraday?s law of induction explains the working principle of transformers, motors, generators, and inductors. The law is named after Michael Faraday, who performed an experiment with a magnet and a coil. During Faraday?s experiment, he discovered how EMF is induced in a coil when the flux passing through the coil changes.
