4. A circular coil that consists of 20 turns of wire is located in a region with a uniform magnetic field, as illustrated below. B out of page coil with 20 turns of wire and R = 1.3 Q The coil has a radius of 12 cm and a total resistance of 1.3 N. Suppose the magnitude of the magnetic field is initially 0.96 T, and it changes to 0.30 T in a time of 0.060 s. (a) What is the magnitude of the induced current in the coil? (b) In which direction does the induced current in the coil flow? 4. A circular coil that consists of 20 turns of wire is located in a region with a uniform magnetic field, as illustrated below.
