Consider a flat, circular coil of n turns, each of the same radius r, in a uniform magnetic field B. The coil is placed perpendicular to B, i.e., the unit vector normal to the circular area enclosed by the coil is parallel to B. Now suppose the coil is rotated through an angle 0 during time T at a constant angular velocity, so that ends up anti-parallel to B. During the rotation, a voltage & is induced across the coil. Once the rotation stops, the voltage drops back to zero. Starting from Faraday's law of induction, show that for 0 = 180 o Edt = 2anr2B (6.1) Now consider the case for which the the coil is not perpendicular to B, i.e., is at an angle to B. What is the physical interpretation of the quantity S6 Edt
