If the diametrically opposite ends of a superconducting loop are connected by a resistance and the loop is rotating with constant angular speed about the diameter in a homogeneous magnetic field will there be a current in the resistor? I am guessing no because the connected points are exactly similar and hence their potentials must be same but my book thinks otherwise. Even when we use Faraday's Law on the two half loops the currents in the common resistor arm cancel.
