Chapter 8.1, Problem 2dT

At two later instants, $t=t_1\text{and}t=t_1+\Delta t$ the loop is located as shown.

1. Use Lenz’ law to determine whether the flux due to the current induced in the loop is positive, negative, or zero. Explain.
2. Describe the current in the loop during this time interval.

Consider the following student dialogue:

Student 1: “The sign of the flux is the same as it was in part C. So the current here will also be counter-clockwise.”

Student 2: “I agree. If I think about the force on a positive charge on the leading edge of the loop. ¡t points towards the top of the page. That's consistent with a counter-clockwise current.”

Do you agree with either student? Explain.
