South pole of a bar magnet is moved toward the center of the loop of copper wire

Question

South pole of a bar magnet is moved toward the center of the loop of copper wire shown below. Choose the appropriate word choices below that correctly complete the blanks in the following four sentences: The original B field from the bar magnet penetrating the loop points the page. As the pole of the bar magnet is moved toward the loop, the magnetic flux in the loop. Therefore, the loop generates an induced B field that points the page. This induced B field is due to an induced current that flows in the loop. out of, decreases, into, clockwise out of, increases, into, counter-clockwise out of, decreases, out of, clockwise Into, decreases, out of, counter-clockwise out of, increases, into, clockwise

Explanation / Answer

1) The original B field from the bar magnet penetrating the loop points into the page.

2) As the south pole of the bar magnet is moved toward the loop, the magnetic flux in the loop decreases.

3) Therefore, the loop generates an induced B field that points out of the page.

4) This induced B field is due to an induced current that flows counter clockwise in the loop.
