Problem 4 Wireless charging is all the rage, and in this problem, we can inves- tigate some of its basic underpinnings. In pset 6 question 3F, you figured out the general shape of the magnetic field of a loop of wire with a current running through it. Building off this, let's consider the effects of such a loop on an inner loop. That was the beginning A circular coil of 400 turns of wire surrounds a single turn square loop of wire, as shown in Figure 4. Look at the graphs below in Figure 5. The current in the outer coil varies with time as shown in the upper graph. On the lower graph, sketch the induced current in the inner loop. In both graphs, a positive value represents a clockwise current. Add explanatory Figure 4: Circular coil of 400 comments as needed either on the graph or on the back of the page. turns surrounds a square loop Be sure to explain how you determined the direction of the induced of wire. current.
