A long solenoid, with its axis along the x axis, consists of 170 turns per meter of wire that carries a steady current of 15.0 Amp. A coil is formed by wrapping 30 turns of thin wire around a circular frame that has a radius of 9.00 centimeter. The coil is located 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 4.00π rad/s. (The plane of the coil is in the yz plane at t = 0). Obtain the emf generated in the coil as a function of time.

For the description of motion in two dimensions one may use Cartesian coordinates (x(t), y(t)), or plane polar coordinates (r(t), γ(t)), where x(t)=r(t)cos(γ(t)) and y(t)= r(t)sin(γ(t)). Rewrite the kinetic energy T= 1/2 m(x'^2+y'^2) in plane polar c..
