I believe in principle, they are still used in power supplies (even low
power), I've seen references in other books. They are practicaly
bullet-proof. A colleague once described a battle-ship's 20" shell cannon
controller, which used magnetic amplifiers in the gyro-servo control loop.
Rad-hard too :)

I would guess it would, as closed gapless cores are what you want for that.
Also hard ferrites, such as permanent magnets, may also due. Let us know how
it works out.
