Hey, I'm in a high school AP class and am stuck! Can anyone help me with this problem concerning induced emf? I would surely appreciate it. There is a loop of wire, shaped like a square. Each side is 20 cm long. There is a magnetic field directed into the page. What would be the way of finding out what the induced emf in the loop. The back of the book says that the answer is 1.40 x 10^-4 Volts.
