![An L = 49.0 cm wire is moving to the right at a speed of
v = 7.70 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 = 0.850 T and is directed into the screen.
What is the emf & induced in the wire?
ε =
Incorrect
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?
F =
counterclockwise
clockwise
If the moving wire and the rails have a combined total
resistance of 1.55 , 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.
