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 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...
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=0.30 m. A light conducting bar 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, the rails are connected on one end by a R=1.5 resistor. A uniform magnetic field of B -0.25 T is...
6) A vertical pair of parallel conducting rails are separated by a width of 22 cm. They are connected at the bottom by a wire that has resistance 50 m. A uniform magnetic field of strength 2800 mT points perpendicularly to the pair of rails. A 640 gram sliding conducting bar connecting the rails is released from the top and allowed to drop under the influence of gravity. Its acceleration rapidly drops to zero, and the bar continues to fall...

can someone explain these to me? answers are circled (5 pts) 19. Two parallel conducting rails are connected at one end by a resistor. A bar slides on the rails with speed v, in the direction away from the resistor. The magnetic field that is directed into the page. What is the direction of the current induced in the circuit that consists of the bar, rails and resistor? X X X (a) clockwise (b) counterclockwise (5 pts) 20. A horizontal...
Two parallel conducting rails with negligible resistance are 41.0 cm apart and are connected together at one end by an 18.8Ω resistor. A conducting bar, also with negligible resistance, is free to slide along the rails. The system is in a region where a 315 mT magnetic field points perpendicular to the plane of the rails, as shown in (Figure 1). If the bar is pulled along the rails at 5.69 m/s, what's the current in the circuit comprising the...
6) A vertical pair of parallel conducting rails are separated by a width of 30 cm. They are connected at the bottom by a wire that has resistance 50 m2. A uniform magnetic field of strength 2400 ml points perpendicularly to the pair of rails. A 720 gram sliding conducting bar connecting the rails is released from the top and allowed to drop under the influence of gravity. Its acceleration rapidly drops to zero, and the bar continues to fall...
Example Variation Problem 27.30 Two parallel conducting rails with negligible resistance are 50.0 cm apart and are connected together at one end by an 16.8-2 resistor. A conducting bar, also with negligible resistance, is free to slide along the rails. The system is in a region where a 325-mT magnetic field points perpendicular to the plane of the rails, as shown in (Figure 1). Part A How fast should the bar be pulled in order to produce a current of...
