Unformatted text preview: 1. The magnetic field is normal to the plane of the loop and is uniform over the loop. Thus at any instant the magnetic flux through the loop is given by ΦB = AB = πr2 B , where A = πr2 is the area of the loop. According to Faraday’s law the magnitude of the emf in the loop is E= dΦB dB = πr2 = π (0.055 m)2 (0.16 T/s) = 1.5 × 10−3 V . dt dt ...
