Question

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.

In this problem, you will use Lenz's law to explore what
happens when an electromagnet is activated a short
distance from a wire loop.
You will need to use the right-hand rule to find the
direction of the induced current.
