Question

Problem4. The figure shows the opcration of clectromagnetic gencrator. The magnctic ficld is given as B = Boz and the axis of rotation of the conducting loop is along the x-axis. Segments 1-2 and 3-4 of the loop are of length I each, and the other two segments are each of width w. Find the Vemf when the conductor loop starts rotating when the loop is parallel to the x-z plane. (Hint, the case covered in the class was that the loop starts rotating when the loop is parallel to x-y planc.) Slip rings Loop surface nomnal Brushes
