A rail gun uses electromagnetic forces to accelerate a
projectile to very high velocities. The basic mechanism of
acceleration is relatively simple and can be illustrated in the
following example. A metal rod of mass 50.0 gand electrical
resistance 0.500 Ω rests on parallel horizontal rails that have
negligible electric resistance. The rails are a distance L = 7.00
cm apart. (Figure 1)The rails are also connected to a voltage
source providing a voltage of V = 5.00 V .
The rod is placed in a vertical magnetic field. The rod begins to
slide when the field reaches the value B = 0.350 T . Assume that
the rod has a slightly flattened bottom so that it slides instead
of rolling. Use 9.80 m/s2 for the magnitude of the acceleration due
to gravity.
Find μs, the coefficient of static friction between the rod and the rails. Give your answer numerically.

A Rail Gun uses electromagnetic forces to accelerate a projectile to very high velocities. The basic mechanism of acceleration is relatively simple and can be illustrated in the following example. A metal rod of mass m and electrical resistance R rests on parallel horizontal rails (that have negligible electric resistance), which are a distance L apart. The rails are also connected to a voltage source V, so a current loop is formed.The rod begins to move if the externally applied vertical...

2) A rail gun is a weapon that uses magnetic forces to propel a rail up to very high speeds. To accomplish this, a conducting rail is free to slide along conducting wires bent into a U-shape. We will assume that the rail has a resistance of 10Ω and length of 20cm, and we have a very large, IT, magnetic field passing perpendicularly through the rectangular loop created by the rail and wires. There is a switch which can be...
An Electromagnetic Rail Gun. A conducting bar with mass m and length L slides over horizontal rails that are connected to a voltage source. The voltage source maintains a constant current I in the rails and bar, and a constant, uniform, vertical magnetic field B fills the region between the rails (see the figure Part C It has been suggested that rail guns based on this principle could accelerate payloads into earth orbit or beyond. Find the distance the bar...
