In the figure, a metal wire of mass m = 26.5 mg can slide with negligible friction on two horizontal parallel rails separated by distance d = 3.15 cm. The track lies in a vertical uniform magnetic field of magnitude 42.3 mT. At time t = 0 s, device G is connected to the rails, producing a constant current i = 8.74 mA in the wire and rails (even as the wire moves). At t = 51.6 ms, what are the wire's (a) speed and (b) direction of motion?

As shown in the figure, a straight conductor parallel to the "x" axis can slide without friction on the top of two horizontal conducting rails which are parallel to the "y" axis, and at a distance of L = 0.2 m apart, in a magnetic field of magnitude B = 1.5 T and direction -z. A current I = 20 A flows through the conductor in the direction shown. A string is tied exactly at the center of the conductor, passes over a frictionless pulley, having tied at the other end a mass " m " which is suspended vertically. a) Draw the free body diagram of the conductor b) Calculate the magnetic force vector on the conductor c) If the driver is at rest, calculate the mass m in grams

A device called a railgun uses the magnetic force on currents to launch projectiles at very high speeds. An idealized model of a railgun is illustrated in the following figure. A 1.2 volt power supply is connected to the two conducting rails. A segment of copper wire, in a region of uniform magnetic field, freely slides on the rails. The wire has a 0.85 mΩ resistance and a mass of 5.0 g. Ignoring the resistance of the rails, when the power supply is connected a) what is the current in the circuit? b) what are the magnitude and direction of the force on the wire? c) what will be the wire's speed after it has slid a distance of 1.0 mm?
