Part 1#

As the conducting ring enters the magnetic field, \(\textrm{(a)}\), what direction is the induced current, if any, flowing through the ring?

Answer Section#

  • A counterclockwise current is induced in the ring.

  • A clockwise current is induced in the ring.

  • No current is induced in the ring.

Part 2#

When the conducting ring is fully inside the magnetic field, \(\textrm{(b)}\), what direction is the induced current, if any, flowing through the ring?

Answer Section#

  • A counterclockwise current is induced in the ring.

  • A clockwise current is induced in the ring.

  • No current is induced in the ring.

Part 3#

As the conducting ring exits the magnetic field, \(\textrm{(c)}\), what direction is the induced current, if any, flowing through the ring?

Answer Section#

  • A counterclockwise current is induced in the ring.

  • A clockwise current is induced in the ring.

  • No current is induced in the ring.
