So a ring launcher launches aluminum hard drive platters a few feet in the air. A pulse cap (like a Maxwell Monster 7kJ type) to the ring launcher and it punches holes in the ceiling (Thankfully not from experience but from stories I've heard). Anyway, I know that you can have a 500lb pull magnet and if you try to climb a HVAC Duct with it, nothing is going to happen, because there isn't enough iron in the sheet metal to support the full electromagnetic field. What I would like to know is, does the same rule apply with a ring launcher? Is there a theoretical maximum power for one launching an aluminum hard drive platter? What kind of power are we looking at? Thanks!

I guess the theoretical maximum would be if the platter was torn apart or melted before the launch pulse was complete. It's pretty high. The DoD chose the repulsion principle for their experimental coil mortar.
