Consider viewing down on a square wire loop, side 25 cm, with an effective resistance of 20 Ω. The loop has a uniform magnetic field passing though it perpendicular to the loops’ area and pointing out of the page. The magnetic field strength changes from 3.2 T to 6.8 T in 0.5 s. (a) What is the magnitude of the induced current in the loop? (b) What is the direction of the current?
