A circular loop of radius 5.0 cm and resistance 0.4 Ω lays in the horizontal XY plane. A uniform magnetic field is established pointing upwards, that's to say, in the direction of the positive Z axis. At t = 0, the magnitude of the magnetic field is 120 mT, but then it is increasing at a rate of 40 mT/s. Find the induced current in the loop at t = 1 s, and discuss whether its direction is clockwise or...
