1. A rod (length = 10 cm) moves on two horizontal frictionless conducting rails, as shown below. The magnetic field in the region is directed perpendicularly to the plane of the rails and is uniform and constant. If a constant force of 0.60 N moves the bar at a constant velocity of 2.0 m/s, show that the current through the 12-2 load resistor is 0.32 A. 1222 An ideal step-down transformer has 200 primary turns and 50 secondary turns. If...

An electron moves through a region of crossed electric and magnetic fields. The electric field E = 2 000 V/m and is directed straight down. The magnetic field B = 0.80 T and is directed to the left. Specify the directions of electric and magnetic forces on the electron if it moves into the paper. For what velocity v of the electron will the electric force exactly cancel the magnetic force? A rod(length = 10 cm)...

The figure below shows a top view of a bar that can slide on two frictionless rails. The resistor is R = 5.00 Ω, and a 2.50-T magnetic field is directed perpendicularly downward, into the page. Let ℓ = 1.20 m. A vertical bar and two parallel horizontal rails lie in the plane of the page, in a region of uniform magnetic field, vector Bin, pointing into the page. The parallel rails run from left to right, with one a...

A DC generator can be built as shown in the figure below. The bar, load (R), and rails form a closed circuit. The two rails are separated a distance d- 2m and the load resistance is R- 10Q. Assume the rails and bar are perfectly conducting and the bar moves to the right at a constant velocity v-10 m/s. The magnetic flux density is constant, directed upward, and equal to B-1 T. Suppose the rails in the figure resistance per...
