Question

jacques moves a bar magnet near a circle of copper wire. moving the magnet creates a changing magnetic field passing through the copper loop. what happens to the copper wire because of the moving magnet? a. the copper wire develops a negative electric charge. b. the copper wire develops a positive electric charge. c. the copper wire carries an electric current. d. the copper wire loses its magnetic charge.

Explanation:

According to Faraday's law of electromagnetic - induction, when a changing magnetic field passes through a closed - loop conductor (like the copper wire loop), an electromotive force (emf) is induced. This emf causes an electric current to flow in the conductor.

Answer:

C. The copper wire carries an electric current.
