Can you charge a capacitor from the collapsing magnetic field of a coilgun? Answered
I was thinking about making a coilgun; not too powerful, only a small, compact (ish) version.
Problem is, the capacitor takes a while to charge.
What I was wondering is whether you return electricity from the collapsing magnetic field of the coil (after firing a shot) back to the capacitor, thus reducing charging time?
And another thing; does a coilgun produce a weak EMP or something when it fires?
