A square loop consists of a single turn with a resistance of 6.00 Ω. The loop has an area of 600 cm2, and has a uniform magnetic field passing through it that is directed out of the page. The loop contains a 12-volt battery, connected as shown in the figure below.
At the instant shown in the figure, there is no net current in the loop. At what rate is the magnitude of the magnetic field changing? The answer should be in T/s.
