Magnetic forces can be used to accelerate projectiles to very high speeds in a so-called railgun. In the simplified version shown below, a voltage source drives current down two parallel ideal wires to a section of metal in contact with both wires. The metal has a resistance 0.6 mΩmΩ and weights 6 grams. We assume that the contacts between the wires and the section of metal are friction-less and that the metal can slide along the wires for a total distance of 1 m before exiting the railgun as a projectile. Our goal is to calculate what voltage that will cause the metal projectile to leave the railgun at the speed of sound (343 m/s), assuming it starts from rest. First, what constant force (in N) will accelerate the rod to the speed of sound in 1 m? Give your answer to 3 significant digits. Next, which voltage V will generate the necessary current to create this constant force? Give your answer to 3 significant digits.

Show that both methods give the same answer. Use the right hand rule to figure out which end of the bar (A or B) will be at a higher potential due to the motion of the conductor in the field.

6. Rail guns have been suggested for launching projectiles into space without chemical rockets. A tabletop model rail gun (Figure A2.4) consists of two long, parallel, horizontal rails, l= 3.50 cm apart, bridged by a bar of mass m= 3.00 g that is free to slide without friction. The rails and bar have low electric resistance, and the current is limited to a constant I = 24.0 A by a power supply that is far to the left of the figure, so it has no magnetic effect on the bar. Figure A2.4 shows the bar at rest at the midpoint of the rails at the moment the current is established. We wish to find the speed with which the bar leaves the rails after being released from the midpoint of the rails. (a) Find the magnitude of the magnetic field at a distance of 1.75 cm from a single long wire carrying a current of 2.40 A. (b) For purposes of evaluating the magnetic field, model the rails as infinitely long. Using the result of part (a), find the magnitude and direction of the magnetic field at the…
MRI: Magnetic resonance imaging (MRI) uses a very strong magnet to create an image. The maximum strength of the magnetic field is 1.5 T. Because the magnet is switched on and off quickly, it can induce large eddy currents in metal objects. Suppose a patient is wearing a metal ring with a radius of 1.4 cm and a mass of 110 g. Such a ring has a resistance of about 0.016 N. If the magnet in the MRI rises from 0T to its maximum strength of 1.5 Tin 1.94 ms, what is the maximum current that could be induced in the ring?
