Problem 30.128

An 8.0 cm * 8.0 cm square loop is halfway into a magnetic field perpendicular to the plane of the loop. The loops mass is 10 g and its resistance is 0.010 . A switch is closed at t = 0 s, causing the magnetic field to increase from 0 to 1.0 T in 0.010 s. a. What is the induced current in the square loop? b. With what speed is the loop kicked away from the magnetic field? Hint: What is the impulse on the loop?
