A spherical balloon with a volume of 2.5 L is in a 55 mT uniform, vertical magnetic field. A horizontal elastic but conducting wire with 2.5 Ω resistance circles the balloon at its equator. Suddenly the balloon starts expanding at 0.75 L/s. Assume that the resistance of the wire does not change. What is the current in the wire 2.0 s later?
