I was wondering if anyone could give me suggestions on good metals to use as the projectile and where to purchase them? So far I had silicon iron suggested... but I can't seem to find any place that sells it. I need about a foot long section of 3/8" diameter or less... thanks for any help you may be able to offer.

If you use a solid projectile, there will be eddy currents in the projectile that reduce the force below what you might expect from a magnetostatic calculation. There are some interesting thoughts with respect to this issue at http://web2.iadfw.net/jd4usa/projectile1.htm Dave Meeker |
