2. The component of the external magnetic field along the central axis of a 50-turn coil of radius 5.3 cm increases from 0 T to 1.8 T in 3.3 s. (a) If the resistance of the coil is 2.8 92, what is the magnitude of the induced current in the coil? (b) What is the direction of the current if the axial component of the field points away from the viewer?
