Hey, I've seen a few posts on this without any responses I really thought helped (at least help answer my question).(adsbygoogle = window.adsbygoogle || []).push({});

So, I was hoping somebody on the forums here could help walk me through the basic physics of a coilgun. Basically, how could you characterize the magnetic field inside the inductor/solenoid in such a way that it's averaged or gives an approximate value? Also, how do you characterize the projectile as a charge, when it isn't actually charged (if that makes any sense). I know the force is the cross product of the magnitude of the charge times the vector v (which for the life of me I can't find what that represents in any material I've seen online), crossed with the magnetic field.

If anybody can walk me through the equations on this, I'd appreciate it. I only took one course in electronics and magnetism years ago, so if you explain it to me, you might need to walk me through one equation at a time, and one variable at a time.
