4. A square loop of wire, 40 cm on each side, has a total resistance of 0.14 . The loop is moved at constant speed in 0.20 s from position I where the magnetic field is 1.3 T to position II where the magnitude of the magnetic field is zero. What is the magnitude and direction of the induced current in the loop? (A) No current is induced. B 2.0 A, counter-clockwise C 2.0 A, clockwise (D) 7.4 A, counter-clockwise Position I B Position II
