A long solenoid is oriented such that its axis is the x-axis, and its center is at the origin of the coordinate system. The solenoid consists of 230 turns of wire per meter and carries a steady current of 15.0 A. The current in the solenoid travels counter-clockwise when viewed from the positive x-axis. Inside the solenoid is a thin circular coil consisting of 30 turns of wire and has a radius of 7.00 cm. The coil is mounted such that its center is also at the origin, and at time t = 0 the plane of the coil is in the yz-plane. The coil rotates about the y-axis (which goes through its diameter) at a constant angular speed of 3.007 rad/s counter-clockwise when viewed from the positive y-axis. What is the emf generated in the coil as a function of time ? Express your answer in units of volts, but do not include units in your expression. For the sign convention, assume the area vector perpendicular to the coil initially points in the +x-direction at t = 0. (Assume t is in seconds.) E
