thank you Warpspeed for the ideas, however, the linear motors I was finding can't produce enough force over enough distance or are too loud.
my last idea was to use wire with a lower resistance than the copper I'm currently using. The projectile I'm trying to launch with this setup is very low...
first of all i would like to appologize if this is in the wrong place. That said, I need help building 2 small opposite pole electromagnets to move a pair of small rare earth magnets back and forth approx. 1-2 inches along a rail.
