How can I get a higher projectile velocity for my coilgun? Answered
I made a coilgun using 8 capacitors of 50V and 4700uf connected in parallel and powered by 4 batteries of 9V each. The coil is wound around a plastic tube over a length of 2 cm. However the projectile (an iron nail of 1 inch just popps out of the tube). How can I fire it at a higher velocity?
