BUT, a steel magnet will also instantly lose much of its "charge" when 
the magnetic circuit's broken, either by removing the magnets or 
removing the armature. The best way to charge it is with a big charger 
and pole pieces that allow charging them in the intact mag after final 
assembly. Alternatively, you can charge them and use "keepers" across 
the poles to maintain the magnetic circuit as the magnet's removed from 
the charger, letting the "keepers" be pushed off as the magnet slides 
onto the mag. I've used brake disk pads as keepers on my M's magnets, 
and the thing works.
