Electromegnetic induction unerstanding changing flux

    1. The problem statement, all variables and given/known data
    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.


    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).
