Permanent magnet motors put out more HP in a given volume than AC induction motors and DC motors with a wound field. So It's obvious that using permanent magnets is an advantage when it comes to size. All the solenoids with plungers that I have seen do not have a magnetized plunger. I was wondering if a magnetized plunger was used if more force could be got from a smaller package. Thanks, Eric
