A coil is made up of N = 20 turns, which are arranged according to two equal semicircles, of radii a = 10 cm, located in two planes orthogonal to each other. Such coil rotates with angular velocity w = 100 rad/s around the axis identified by the intersection of the two planes and is immersed in a magnetic field B = 0.5 T uniform and constant, orthogonal to the rotation axis. Calculate the e.m.f. E;, its maximum value &max, the average power developed if the total resistance of the coil is R = 10 S2.
