Think you could do a before/after radiation check for alpha radiation
emission from neutron activation? Rich Hull and other fusion researchers
might find the results interesting.

What is the propagation velocity of the magnetic field? Should be quite high
I would think. Anyways, the (reluctance?) or permiability difference between
air and even pwdrd iron (150) would make leakage negligable.
