Question

In the figure, a conducting rod of length L= 32.0cm moves in a magnetic field B? of magnitude 0.480T directed into the plane of the figure. The rod moves with speedv= 4.00 m/s in the direction shown.

When the charges in the rod are in equilibrium, what is the magnitude E of the electric field within the rod?

E= _______ V/m

What is the magnitude Vba of the potential between the ends of the rod?

Vba= __________ V

What is the magnitude E of the motional emf induced in the rod?

E=________ V
