ALNICO V magnetic cores which are one of the most powerful permanent magnet alloys available.
Stir bars should not be stored in a random mass or dropped on a hard surface, especially steel.
Stir bars should be stored in pairs to maintain magnetic strength.
In general PTFE thickness accounts for 18% of stir bar diameter.
