Back in 1960's the guy who I worked for had been
in radar during the war.
We had several magnetrons about the place. They had a very strong permanent magnet.
He always said when the Germans recovered a magnetron from a crashed bomber they soon
worked out how it oscillated at 10Ghz but making the magnet was beyond them.

I suspect the working area in a magnetron is too small for this purpose, unless you break
it up.
A rare earth magnet savaged from a disk drive or a banned child toy (aka BuckyBalls) might
be more effective.
