1. Match the following to the correct word:
    The phenomenon due to which a changing
    magnetic field within a closed copper coil
    produces an electric current in the coil
    A device which increases the emf of the
    current.
    A device which converts mechanical energy
    into electric energy.
    A device which decreases the emf of the
    current.
    The alternating current produced in a closed
    coil due to the change of magnetic lines of
    forces in the coil.
    Induced Current
    Electric generator
    Step up Transformer
    Step down Transformer
    Electromagnetic Induction

Verified Answer :

Final answer:

Electromagnetic Induction involves generating electric current from a changing magnetic field. Transformers play a role in altering the emf of the current.


Explanation:

Electromagnetic Induction is the phenomenon where a changing magnetic field within a closed copper coil generates an electric current. A Step-up Transformer increases the emf of the current, while a Step-down Transformer decreases it. Induced current is the alternating current produced in a closed coil due to changing magnetic lines of forces.
