Some friends and I conducted an experiment with a large electromagnet. My bank of capacitors consisted of 28 560 Micro Farad capacitors at 250 Volts. All of them were in parallel. The total combined capacitance was 15,680 MF. @ 250 volts. I'm not sure how many feet of 10 gauge wire I used, but it weighed about 6 pounds.
Someone asked how I know which direction the metal bar will travel. Here is my answer.
Because I pulled the metal bar a few inches out of the coils center, the moment I energized the coil it's magnetic field pulls the bar back towards the center, Normally the magnetic field would keep the bar held in the center if I had used a steady power source, but because I used a charged capacitor, it instantly discharges after pulling the metal bar, allowing it to continue traveling out the opposite side of the coil from which I've pulled the bar away from.
