An L = 55.0 cm wire is moving to the right at a speed of
v = 6.90 m/s across two parallel wire rails that are connected
on the left side, as shown in the figure. The whole apparatus is
immersed in a uniform magnetic field that has a magnitude of
B = 0.750 T and is directed into the screen.
What is the emf E induced in the wire?
E =
V
The induced emf causes a current to flow in the circuit formed
by the moving wire and the rails.
In which direction does the current flow around
the circuit?
counterclockwise
clockwise

If the moving wire and the rails have a combined total
resistance of 1.35 2, what applied force F would be required
to keep the wire moving at the given velocity? Assume that
there is no friction between the moving wire and the rails.
F =
N
