Q47: A long solenoid, with its axis along the x axis, consists of turns per meter of wire that carries a steady cur- rent of A. A coil is formed by wraping turns of thin wire around a circular frame that has a radius of cm. The coil is placed inside the solenoid and mounted on an axis that is a diameter of the coil and coincides with the y axis. The coil is then rotated with an angular speed of p rad/s. The plane of the coil is in the yz plane at t = 0. Determine the emf generated in the coil as a function of time.
