These neodymium stir bar magnets consist of a powerful neodymium magnet encased in a molded layer of PTFE. The shape includes a molded ridge, or pivot ring to make rotation easier and smoother.
Stronger than comparable Alnico magnets, these neodymium stir bars do not tend to demagnetize over time. Made with N42H grade magnets, these magnets are suitable for high temperatures up to 120ºC.
