I am also interested - I believe that this thread "fizzled out" last 
time.  I had even collected a large number of magnetron magnets, although 
these are now in service on our refrigerator door.

Tackled magnets in grammar school (high school) physics, but hardly touched 
on them doing EE at college, except in specific applications.  In other 
words, I can remember very little about them.

I assume that the amount of quench would be directly proportional to the 
amount of magnetic flux.  How does one increase the flux - stack of magnets 
in series with iron pole pieces to either side of the gap?

Trick question: does the north of a compass needle point to the north or 
the south pole of a magnet?  I would say it would point to the SOUTH of the 
magnet.
