1. A conducting square loop with side lengths of L is initially in a magnetic field with a strength of 0.5 T directed out of the page as shown in the diagram below. The field strength changes to a value of B during 0.5 seconds.
2. What is the change in flux (4 points)?L = 0.50 m B = 4.0 T R = 20

1. What is the induced emf (4 points)?

1. If the total resistance of the loop is R, what is the current in the loop (2 points)?

d. What is the direction of the current through the resistor (2 points)?
