  That's nothing, go find a state of the art perm magnet synchronous machine
(brushless DC in laymans terms) and get the mags off the rotor.  Technology
gets these things over 1.2T in a 1.5x0.75x0.125 package.  They will
demagnetize every other type of magnet I have ever seen.  They are also
explosive if machined.  Fun stuff;)
