Homework Help: Force generated by a solenoid

  1. Apr 26, 2010 #1
    1. The problem statement, all variables and given/known data
    I am building a coil gun with a single solenoid. I am going through the equations I know for magnetic force and others but I don't know if I am finding the force the wire feels or if it will be the force the projectile undergoes.


    2. Relevant equations
    F=qvB (assuming that everything that needs to be constant and uniform is)
    B=(uNI)/L (where u is the permeability of free space)


    3. The attempt at a solution
    I don't know how to get an equation for force that does not have charge since the projectile is not charged. I know there is some way to do it but I can't find it. Any help as to how I can I find the force the projectile undergoes would be greatly appreciated.
