Suppose that the light bulb in Figure 22.4b is a 60.0-W bulb with a resistance of 210 Ω. The magnetic field has a magnitude of 0.489 T, and the length of the rod is 1.42 m. The only resistance in the circuit is that due to the bulb. What is the shortest distance along the rails that the rod would have to slide for the bulb to remain lit for one-half second?

4. Suppose the light bulb in the figure below is replaced with a short wire of zero resistance, and the resistance of the rails is negligible. The only resistance is from the moving rod, which is iron (resistivity - 9.90 x 10 m ). The rod has a cross-sectional area of 3.10 x 10 m. and moves with a speed of 2.60 ms. The magnetic field has a magnitude of 0.055 T. What is the current in the rod?

A square rod has a resistance R and slides without friction down parallel conduction rails of negligible resistance, as shown in the figure. The rails are connected at the bottom so that the square rod and the rails form a conducting loop. The rails are inclined at an angle 0 = 45° to the surface. A uniform magnetic field B exists throughout the region along the Z-direction. The length of the square rod is L. For the coordinate system given...

The conducting rod shown in the figure has length L and is being pulled along horizontal, frictionless, conducting rails at a constant velocity. The rails are connected at one end with a metal strip. A uniform magnetic field, directed out of the page, fills the region in which the rod moves. Assume that L 8.3 cm, the speed of the rod is v = 4.4 m/s, and the magnitude of the magnetic field is B = 1.0 T. (a) what...

2) A rail gun is a weapon that uses magnetic forces to propel a rail up to very high speeds. To accomplish this, a conducting rail is free to slide along conducting wires bent into a U-shape. We will assume that the rail has a resistance of 10Ω and length of 20cm, and we have a very large, IT, magnetic field passing perpendicularly through the rectangular loop created by the rail and wires. There is a switch which can be...
