The problem with magnetic weapons like Gauss rifles and rail guns is that you need a lot of electricity very quickly. The only way to get this is by charging a huge bank of capacitors beforehand. But perhaps there is another way.
Piezoelectric materials generate a voltage when squeezed. Hitting a
piezoelectric crystal with a hammer causes a visible electric arc. But the power generated like this is pretty puny.
Proposed, therefore, is a replica of a fission bomb, with the nuclear fuel replaced with (much cheaper) piezoelectric material. This can either be an implosion- or gun-type device, depending on where it's easiest to attach the crocodile clips. When the (conventional) explosive charge is fired, we should get a whole bunch of electrons jumping out of the jump leads.
The advantage of all this is that the device could be produced in bulk, in cartridge form, and loaded into a (possibly cumbersome) magazine, so that your futuristic magnetic weapons can now be semiautomatic.
A spin-off business will also market a miniaturized version of the system for speeding up the recycle time of photographic strobe lights.
A book about such things...

||Ah. Yes. Those too. But they still need charging beforehand.
||More on topic, I'm not sure you'll get enough current out of
your device. Tests are in order!
||You could fire a rail gun at the piezo elements.
||Re [Ling]'s link: Why didn't I think of this sooner? Just use an
EPFCG! [link] Those are well-studied already.
||Also, [Ling], your link is in Thai. Is that your native language?

Heh, I assure you, the book is in English!
I know enough Thai to get into trouble, but not enough to get
out of it.
