The generation of an electric current in a closed circuit by a changing magnetic field is 1) electromagnetism2) electromagnetic induction3) electromagnetic spectrum4) electromagnetic force.

The correct answer is option 2.

Explanation:

When any closed circuit is kept in the varying magnetic field small amount of  electromotive force is generated in the in the circuit which gives rise to generation of electric current in a circuit. This phenomena of the induction of the electricity is named as electromagnetic induction.

This phenomena was discovers by Micheal Faraday.

mendel's first law states that during the formation of reproductive cells , pairs of hereditary factors for a specific trait separate so that offspring receive one factor from each parent.
