I am building a coilgun and I have constructed a coil with several thousand turns, an ohm meter measures its resistance at 300 ohms, so I am having trouble powering it, I ran 240v through it and got nothing, it barely moved a paper clip. According to my calculations, I need to run 1000 volts at the minimum through the coil in order for it to work. From my research there are three ways to do that:
1)A really big transformer (such as a microwave transformer)
2)A Marx Generator
3)or with a Voltage Multiplier.
A Marx generator seems like it would be perfect for a coilgun, as it releases an extremely high voltage, high current pulse in a small amount of time, but it seems like a rather dangerous build. You are supposed to connect the voltage multiplier to the Marx Generator, but wouldn't it be easier to just to make more multiplier stages and remove the Marx Generator entirely? I've seen voltage multipliers go up to 15kv, which is more than enough.
