A metal rod with a length of 30.0 cm lies in the xy-plane and makes an angle of 36.5° with the positive x-axis and an angle of 53.5° 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 B =(0.190T)i^−(0.210T)j^−(0.0400T )k^. Required:
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.
