Resonant coil launcher

Could a resonant primary coil from a tesla coil be used to launch many BBs at low velocity?

I think not since the primary of a TC doesn't reach the currents usually associated with projectile launching.
Also, for projectile launching, you need a single pulse while the waveform at the primary of a TC is continuous.
I think what you would see is the same thing as putting a bunch of nails into the window of a 60Hz transformer.
You'd get a bunch of vibrating nails that tended to stick to each other.

I doubt there's a way to launch BBs individually if they are in a group at the start of the pulse since the
magnetic field induces magnetic moments in each that point in roughly the same direction (think sticking a
bunch of magnets N to S). You could, however launch a mass of BBs at something tongue

Yeah, as Myke said, that wouldn't work...
You'd need some sort of feeding mechanism if you want to fire many projectiles after each other. Just lining them up will make them stick to each other when the coil gets current,
