Rail Guns: Dual Rods & Current Flow

Click For Summary
SUMMARY

This discussion centers on the mechanics of rail guns, specifically the behavior of dual rods under current flow. It concludes that while both rods would move down the rails due to the clockwise current, their interaction depends on the design of the rail gun. The conversation also references particle accelerators, such as the Stanford Linear Accelerator (SLAC), which manage multiple charged particles effectively by utilizing microwave surfing techniques to minimize repulsion between electrons.

PREREQUISITES
  • Understanding of rail gun mechanics

Ok, so we learned about rail guns today (they are so freakin' cool), and I understand how it moves one rod down the rails... however, what happens if there are two?
Won't both move down the rails (away from battery) since the current is flowing clockwise, or will they repel each other?

Well, that's more of an engineering question than anything else. It would depend on the design of the gun.

Particle accelerators, like the Stanford Linear Accelerator, propel multiple charged particles at the same time by (in the case of SLAC, at least) having them "surf" on microwaves. The electrons would repel each other, but they're far enough apart that the design of the accelerator minimizes the effects of that interaction.
