A 100-turn coil is rotating with a constant angular speed in a uniform magnetic field of 0.486 T that is perpendicular to its surface at t= 0 s. The diameter of the coil is 10 cm. Calculate the magnitude (i.e., positive value) of the electric charge induced in the coil during half a revolution, in mC, if the resistance of the coil is 39.7 N. Calculate i like in the previous problem, and then solve the integral J i- dt to find the induced charge (T is the period).
