Question

What did Faraday show in 1831?

Options

• Electricity and magnetism are separate and unrelated phenomena

• A moving magnet can produce an electric current in a conductor

• A coil is a long coil of wire that produces a magnetic field

• A stationary magnetic field always produces an induced current

Answer 1

Faraday showed in 1831 that a moving magnet can produce electric current in a conductor. The moving magnet changes the magnetic field experienced by the conductor.
