Question

Which of the following will cause an induced current in a coil of wire? Which of the following will cause an induced current in a coil of wire? a magnet resting near the coil the constant field of the earth passing through the coil a wire carrying a constant current near the coil a magnet being moved into or out of the coil

Answer 1

Answer:

a magnet being moved into or out of the coil

Explanation:

Electromagnetic induction on a coil of wire depends on relative motion between the wire and a magnetic field. If there is no relative motion between the magnet and the coil, no current is included on the wire. This implies that a stationary magnet around a coil of wire will not produce induced current on a stationary conductor or wire.

Summarily, whenever a conductor is placed in a changing magnetic field, current is induced on the conductor.
