This thread caught my interest enought to go to the local ACE hardware
store and buy a couple replacement brushes for DeWalt miter ans circular
saws.  Each package contains two brushes approximately 1/4" x 1/2" x 3/4"
and both sets I bought appear to be diamagnetic.  DeWalt part number
DW4001BR.  I used small magnets out of the positioning system of old CDROM
drives for the levitated magnet and magnets out of the positioning actuator
of old hard drives.  I think both are rare earth as they have an extremely
strong pull.
