Answer:
Step-by-step explanation:
In order to produce an electric current in a coil of wire, a magnetic field must be changing or varying in strength or direction, relative to the coil. This changing magnetic field induces an electric current in the wire coil, according to Faraday's Law of Electromagnetic Induction. The strength of the induced current depends on the rate of change of the magnetic field, the number of turns in the coil, and the resistance of the wire.
