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...
Please help on physics question An aluminum bar is moved across conducting rails as shown below. A constant external magnetic field is directed into the page. The length of the bar is 1.20 m. The magnitude of the external magnetic field is 2.50 T. The resistance R is 6.00 Ohm. At what speed (in m/s) should the bar be moved to produce a current of 0.500 A in the resistor?
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...
