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...

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...

A conducting bar slides without friction on two parallel horizontal rails that are 50 cm apart and connected by a wire at one end. The resistance of the bar and the rails is constant and equal to 0.10 0. A uniform magnetic field is perpendicular to the plane of the rails. A 0.080-N force parallel to the rails is required to keep the bar moving at a constant speed of 0.50 m/s. What is the magnitude of the magnetic field...
