Rail gun weapons are not only popular in video games, they are actually being developed by the Navy for practical use. The figure below shows a simple model of how a rail gun works. The entirety of the rail gun is immersed in a magnetic field of strength B = 0.56 Tesla. With the switch open, the capacitor on the left is charged to a very high voltage Vo = 9900 Volts. When the switch is closed current will flow through the bar and thereby exert a magnetic force on the bar pushing it to the right. The bar has a mass M = 1.79 kg, a resistance R = 0.194 N, and a length L = 0.246 meters. We shall assume that the rails have zero resistance, and that the bar slides without friction. The bar exits the rail gun after having accelerated over a distance of d = 3.92 meters. Immersed in a Magnetic Field Mass M V. Resistance R Length L switch d Calculate the current flowing through the bar when the switch is closed I = Amps Calculate the force on the bar due to the magnetic field F = Newtons Calculate the acceleration of the bar a = m/s2 Assuming the bar experiences constant acceleration, find the velocity of the bar when it leaves the rails: v(x=d) m/s

A circular coil enclosing an area of 140 cm? is made of 210 turns of copper wire (shown in the figure below). The wire making up the coil has no resistance; the ends of the wire are connected across a 3.00-N resistor to form a closed circuit. Initially, a 1.20-T uniform magnetic field points perpendicularly upward through the plane of the coil. The direction of the field then reverses so that the final magnetic field has a magnitude of 1.20 T and points downward through the coil. If the time interval required for the field to reverse directions is 0.200 s, what is the average current in the coil during that time? R

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?
