A metal rod of length L moves with velocity v perpendicular

A metal rod of length L moves with velocity v perpendicular to its axis and to a constant B field as shown. You will work in SI units. Write an expression for the force on charges in the rod by virtue of the motion of the rod. What is the potential difference between the ends of the rod?

Solution

a) F = q*(VxB) = qVB

b) potential difference = VBL
