A 25.0-cm-long metal rod lies in the xy-plane and makes an angle of 36.9^o with the positive x-axis and an angle of 53.1^o with the positive y-axis. The rod is moving in the +x-direction with a speed of 6.80 m/s. The rod is in a uniform magnetic field (a) What is the magnitude of the emf induced in the rod? (b) Indicate in a sketch which end of the rod is at higher potential.
