First off this inductor is for a dc/dc boost converter. I plan on bringing 9v up to about 200. I haven't decided on a final frequency yet, but it would probably be something around 1.5KHz. I'm not sure what the original frequency of the power supply is because I don't own an oscilloscope.The core is shaped kind of like El , kinda hard to illustrate. It's 1.5 inches long, 2 inches tall, and half an inch thick. And I have absolutely no idea what it's made of. But judging from
THIS website it is probably a ferrous alloy powder E core.
A coilgun is the not so correct name for an electromagnetic projectile accelerator. Basically a bank of capacitors is charged to a high voltage and/or high amperage. Then the current is forced all at once through a coil of wire, kind of like a solenoid. The magnetic field caused by the coil attracts a ferrous projectile that is inside a tube that runs through the coil. The current is then shut off once the projectile reaches the middle of the coil and the projectile leaves the front of the barrel.
