A metal bar slides along the "U" shaped metal wire as shown in the figure above.
The bar, which has negligable resistance, slides with a speed v=n1
meters/sec., on the "U" shaped wire. There is a magnetic field perpendicular to
the page that has a magnitude of n2 Tesla. The width of the "U"
shaped wire is 0.5 meters, and the resistance of the wire is 2 Ω. What is
the current I in Amps that flows in the wire? That is, if I=n3 Amps,
what is n3?
