Chapter 8.1, Problem 2aT

The diagram at right shows a stationary, copper wire loop in a uniform magnetic field. The magnitude of the field is decreasing with time.

1. Would you predict that there would be a current through the loop:

• if you were to use the idea that there is a magnetic force exerted on a charge moving in a magnetic field? Explain your reasoning.

• if you were to use the reasoning of the student in part D of section I with whom you agreed? Explain.

2. It is observed that there is an induced current through the wire loop in this case. Use the appropriate reasoning above to find the direction of the current through the wire of the loop.
