right with a constant speed of 6.00 m/s?
b) At what rate is energy dissipated in the 4.00 ohm
resistor?

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...

A conducting rod with length L, is to slide without friction on horizontal infinitely long metal rails connected through resistance R as show in Fig. uniform magnetic field B is directed out of the plane of the figure. What is the applied force F required to move the bar to the right with a constant speed At what rate is energy dissipated in the resistor R?
A conductiong bar of mass m is place on two long conducting rails a distance l apart. The rails are inclined at an angle ? with respect to the horizontal, and the 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 oriented perpendicular to the incline. A resistor of resistance R connects the upper ends of the rails and completes the circuit as...
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...
ocer long metal bar with a mass of 50-kg is falling with a constant velocity of 20 m/s towards the earth. The bar is attached to two conducting rails as shown. Ignoring air resistance and friction, determine the emf in the circuit if there is a uniform magnetic field directed perpendicular to the motion of the bar. The resistor has a value of 100. Vertical Conducting Resistor
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...
