Question

question 8 of 20
in an electric generator, a turning loop of wire is placed between two permanent magnets causing electromagnetic induction in the wire. what sentence best explains the effect of turning loops of wire in an electric generator?
a. magnetic energy changes into electrical energy resulting in an electric current.
b. electrical energy changes into mechanical energy resulting in motion of the wire.
c. magnetic energy changes into mechanical energy resulting in the motion of the wire.
d. mechanical energy changes into electrical energy resulting in an electric current.

Explanation:

In an electric generator, electromagnetic induction occurs when a wire is placed between permanent magnets. The principle is that mechanical energy (from turning the wire) is converted into electrical energy. This is based on Faraday's law of electromagnetic induction.

Answer:

A. Mechanical energy changes to electrical energy resulting in an electric current.
