The beginning of the real deal

The goal, of course, is building an electromagnetic rifle.

A long series of electromagnets will sequentially pull and therefore accelerate a steel projectile down the barrel.

The First image is the making of the barrel. Each electromagnet is several layers of wire with a ferrite shield around them. Each layer must be laid and super glued in place before the next one can be done. Since there are 12 gates and 5 layers each we're talking 60 wrapping sessions.

The size of those magnets has mostly been determined experimentally (some calculations before hand). Their most important attribute is that they're designed to fire a respectable size cap (2mF) in about 100us. They'll need to fire quick if they're to pull a fast moving bullet.
