A 2.4 kg copper rod rests on two horizontal rails (see figure
below) 1.2 m apart and carries a current of 65 A from one rail to
the other. The coefficient of static friction between rod and rails
is 0.51. What are the magnitude and angle (relative to the
vertical) of the smallest magnetic field that puts the rod on the
verge of sliding? (Based on the bottom picture, define to the right

A conducting bar of mass m is placed on two long conducting rails
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...

Two insulated current-carrying wires (wire 1 and wire 2) are bound together with wire ties to form a two-wire unit. The wires are 2.95 m long and are stretched out horizontally parallel to each other. Wire 1 carries a current of I, = 8.00 A and the other wire carries a current I, in the opposite direction. The two-wire unit is placed in a uniform magnetic field of magnitude 0.400 T such that the angle between the direction of I,...

A pair of conducting, parallel, frictionless rails is mounted on an insulating platform. The distance between the rails is L = 0.20 m. The rails are connected on one end by a R = 10.12 resistor. A conducting bar of mass 1.2 kg can slide on the rails without friction. When the conducting bar is at x = 0, the enclosed area of the loop is 0.03 m2. There is zero resistance in the conducting bar or rails. A uniform...
