Question

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 View Available Hint(s)

Answer 1

Answer:

B, B

Explanation:

The fill in the blanks would be;

First blank : decreases

Second blank ; clockwise

The above phenomena is in accordance with Lenz law that states that when an electric current passes through a conductor and there is a change in magnetic field, then an opposing force is always produced.

The direction of magnetic field can be obtained through Right Hand Rule.

When the switch is opened, means the flow of current shall stop and hence the magnitude of flux would decrease
