The figure below shows a top view of a bar that can slide on two frictionless rails. The resistor is
R = 5.00 Ω,
and a 2.50-T magnetic field is directed perpendicularly downward, into the page. Let ℓ = 1.20 m.
A vertical bar and two parallel horizontal rails lie in the plane of the page, in a region of uniform magnetic field, vector Bin, pointing into 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.
(a) Calculate the applied force required to move the bar to the
right at a constant speed of 2.50 m/s.
N (to the right)
(b) At what rate is energy delivered to the resistor?

The figure below shows a bar of mass m = 0.280 kg that can slide without friction on a pair of rails separated by a distance ℓ = 1.20 m and located on an inclined plane that makes an angle θ = 29.5° with respect to the ground. The resistance of the resistor is R = 2.20 Ω, and a uniform magnetic field of magnitude B = 0.500 T is directed downward, perpendicular to the ground, over the entire region...
6. In the figure below, a metal wire of mass m = 24.1 mg can slide with negligible friction on two horizontal parallel rails separated by distance d = 2.56 cm. The track lies in a vertical uniform magnetic field of magnitude B = 56.3 mT. At time t= 0, device G is connected to the rails, producing a constant current i = 9.13 mA in the wire and rails (even as the wire moves). At t = 61.1 ms,...
