In the figure below, a metal bar sitting on two parallel conducting rails, connected to each other by a resistor, is pulled to the right at a constant speed.
A vertical bar and two parallel horizontal rails lie in the plane of the page. The parallel rails run from left to right, with one a distance ℓ above the other. The left ends of the rails are connected by a vertical wire containing a resistor R. The vertical bar lies across the rails to the right of the wire. Force vector Fapp points from the bar toward the right.
In the figure below, a metal bar sitting on two parallel conducting rails, connected to each other by a resistor, is pulled to the right at a constant speed. The resistance
R = 3.00 Ω,
the distance between the rails is
ℓ = 1.20 m,
and a uniform
3.30 T
the magnetic field is directed into the page. At what speed (in m/s) should the bar be moved to produce a current of 0.500 A in the resistor?
