A 0.204 m -long bar moves on parallel rails that are connected
through a 6.05 Ω resistor, as shown in the following figure (Figure
1), so the apparatus makes a complete circuit. You can ignore the
resistance of the bar and rails. The circuit is in a uniform
magnetic field 1.45 T that is directed into the plane of the
figure. At an instant when the induced current in the circuit is
counterclockwise and equal to 1.70 A , what...

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...

A conducting bar of mass m is placed on two long conducting rails a distance l apart. The rails are inclined at an angle theta with respect to the horizontal, andthe bar is able to slide on the rails with negligible friction. The bar and rails are in a uniform and constant magnetic field of magnitude B orientedperpendicular to the incline. A resistor of resistance R connects the upper ends of the rails and completes the circuit as shown. The...
