Hm, so in an ideal solenoid (of infinite length and with no spacing between the coils), a ferromagnetic object would feel no force, correct? So I probably want to keep my coil length pretty short in order to avoid wasting energy creating a relatively homogeneous (and therefore relatively...

Hello, I'm building a coilgun and I'm confused. I understand that within a solenoid, the magnetic field is homogeneous. I've also read that a ferromagnetic projectile in a coilgun is sucked to the center of the coil. If the magnetic field is the same everywhere through the coil, what is...
