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 perpendicular 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.
