Case: Read the below passage and answer accordingly Electromagnetic induction is defined as the production of an electromotive force across an electric conductor in a changing magnetic field. The discovery of induction was done by Michael Faraday in the year 1831. Electromagnetic induction finds many applications such as in electrical components which include transformers, inductors, and other devices such as electric motors and generators. |
