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...

Three frictionless conducting rails are fixed on an incline plane as shown. The top piece has a resistance R. A free conducting rod of mass m length 1 is placed on the rails, forming a closed loop abcd, and pushed with a force ¥ = -Fî. There is an external magnetic field B = B(cosa î + cosß î + cosy k). (a) Find an expression for the induced e.m.f in the closed loop abcd. Find an expression for the...

1) In a region of space with an external magnetic field of 0.55-T in the vertical direction, two metal rails of negligible resistance rest 32 cm apart on a 6° ramp. The rails are joined at the bottom by a 0.60-Ω resistor. At the top of the rails, a copper bar of mass 0.040 kg and negligible resistance is laid across the rails and released from rest. When the copper rod reaches a steady speed, what will be (a) the...

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...

The conducting rod shown in the accompanying figure moves along parallel metal rails that are 25-cm apart. The system is in a uniform magnetic field of strength 0.75 T, which is directed into the page. The resistances of the rod and the rails are negligible, but the section PQ has a resistance of 0.25 Ω. (a) What is the emf induced in the rod when it is moving to the right with a speed of 5.0 m/s? (b) What force is required to...
