1. Suppose that a thin wire is wrapped 25 times around a balloon, and then placed in a uniform magnetic field that has magnitude 1.3 T and points in a direction per- pendicular to the coil of wire. If the balloon is inflated such that its radius increases by 1 cm per second, what will the potential difference generated in the coil be when the balloon has a radius of 5 cm? If the resistance in the coil is 25 Ohms, what will the magnitude of the current be? (Assume that the wire doesn't break as the balloon is inflated.) Make sure to draw a careful picture of this system and indicate the direction that charge will flow
