Question

Part D

Finally, the switch on the electromagnet is reopened. The magnitude of the external magnetic flux through the wire loop ______ (A. increases, B. decreases, C. remains constant), and there is _______ (A. zero, B. a clockwise, C. a counterclockwise) current induced in the loop (as seen from the left).

Enter the letters corresponding to the responses that correctly complete the statement above. For example, if the correct answers are A and C, type A,C

Now consider the new arrangement shown in the figure. (Figure 2) Note that the orientation of the battery is reversed with respect to the first arrangement you considered. Answer the following questions related to the arrangment with the new battery orientation.

Part E

The switch on the electromagnet, initially open, is closed. What is the direction of the induced current in the wire loop (as seen from the left)?

	a.) There is no induced current.
	b.) The induced current is clockwise.
	c.) The induced current is counterclockwise.

Part F

Now the switch on the electromagnet is reopened. The magnitude of the external magnetic flux through the wire loop ______ (A. increases, B. decreases, C. remains constant), and there is _______ (A. zero, B. a clockwise, C. a counterclockwise) current induced in the loop (as seen from the left.

Enter the letters corresponding to the responses that correctly complete the statement above. For example: A,C

Answer 1

D. decreases, Clockwise,

So, B,B

E. b.) The induced current is clockwise.

F.Decreases, Counterclockwise.

So, B,C
