: The first thing I thought of when I saw your coins was..if you can
: shrink
: metal.. can a magnetic field be used to compress a berylium reflector
: sphere with a plutonium core? ie a nuclear bomb. Traditonal explosive
: lenses are used to initiate the core now. Can a magnetic field generate
: the forces comprable to an exlposive lens? I know it can contain nuclear
: fusion ie tokomak . How many Kv would be required and could a field be
: reliably modulated to produce a uniform comression wave on a shperical
: structure.
: Thinking outside of the box.
: : Hi Stan,
: Interesting questions! The quarter shrinker really doesn't shrink metal,
: it reshapes it. As the quarter is reduced in diameter, it increases in
: thickness so that the volume (and thus the density) remains the same.
: I suspect that it is not possible to use magnetic forming instead of
: explosives, since the magnetic compression force is not spherically
: symmetric, nor is the energy density comparable to that which can be
: achieved by shaped charges. The "shrinking" force is strongest
: in the center portion of the coil, dropping off rapidly toward the
: edges, and is directed radially (not spherically) inward. The peak force
: is about 20 microseconds from the time the triggered spark gap fires,
: and the peak force lasts for only a few microseconds (if the coil were
: to survive... which it doesn't).
: I'm not sure I can answer the other questions even if I knew the
: answers... :^)
: Best regards,
