A B C A bar magnet is dropped, south pole down, as shown above, through the center of a loop of wire. The center of the magnet passes through the loop at time $t_c$. Taking the clockwise direction to be positive, what is the correct graph for the current in the loop? A C B

Step 1
As the magnet approaches the loop, the magnetic field through the loop is increasing. According to Faraday's law of electromagnetic induction, this will induce a current in the loop. The direction of the induced current will be such that it opposes the change in Show more…

A bar magnet is held below the center of a wire loop lying in the horizontal plane. The south end of the magnet is toward the loop. After the magnet is pushed upward into the loop, what is the current direction?
Adi S.
A bar magnet is falling toward the center of a loop of wire, with the north pole oriented downward. Viewed from the same side of the loop as the magnet, as the north pole approaches the loop, what is the direction of the induced current? Counterclockwise. Zero. Clockwise.
