A long, solenoid has a turns per unit length, n, and has a current, I, flowing through it. Use Ampere's law to determine the magnetic field inside the solenoid (magnitude and direction). A single, rectangular loop of length, 1, and width, w, is situated in a magnetic field that point out of the page. It rotates such that the angle between the area vector and the magnetic field varies as the angular frequency. co, multiplied by the time, t. Using Faraday's law, determine the induced emf.
