A flat coil of wire consisting of 38 turns, each with an area of 53 cm2, is positioned perpendicularly to a uniform magnetic field that increases its magnitude at a constant rate from 3 T to 10 T in 3.8 s. If the coil has a total resistance of 0.5 ohms, what is the magnitude of the induced current in amperes?
