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 (Figure 1). A 1.2 V power supply is connected to two conducting rails. A segment of copper wire, in a region of uniform magnetic field, slides freely on the rails. The wire has a 0.85 mΩ resistance and a mass of 4.4 g . Ignore the resistance of the rails. The power supply is switched on. What is the magnitude of the force on the wire? What will be the wire's speed after it has slid a distance of 8.0 cm ?
Two meter-long parallel wires each have a linear mass density of 30 g/m and carry the same current of 0.50 mA. The are hung from the same support bar by strings of length .080 m so that the wires run parallel to the ground. The current causes the wires to repel from each other, so they hang with an angle θ = 20◦ between the supporting strings of the two wires. Are the currents in the same or opposite directions? What is the magnitude of the current?

You've decided to make a magnetic projectile launcher for your science project. An aluminum bar of length l = 5.19 cm slides along metal rails through a magnetic field B = 0.664 T. The switch closes at t = 0 s , while the bar is at rest, and a battery of emf = 16.50 V starts a current flowing around the loop. The battery had internal resistance, r = 0.139 Ω. The resistance of rails and the bar are effectively zero. What is the terminal speed (in m/s) of the bar?
