Question

Which of the following describes the production of an electric current by moving a loop of wire through a magnetic field or moving a magnet through a wire loop?

a. magnetic domain
b. electromagnetic induction
c.magnetic poles
d.electromagnetism

Answer 1

Answer: b. electromagnetic induction

Explanation:

• Electromagnetic induction is the production of electromotive force (electric current ) by changing the magnetic field.

By moving a magnet through a wire loop , the magnetic field changes.

Thus, the electromagnetic induction describes the production of an electric current by moving a loop of wire through a magnetic field or moving a magnet through a wire loop .

Answer 2

The production of an electric current by moving a loop of wire through a magnetic field or moving a magnet through a wire loop is called electromagnetic induction.
