Summary:A magnetic stir element (10) includes a stirrer (12) of nonmagnetic material that is configured for stirring the contents of a vessel. The stirrer includes a pair of opposed cavities (15) on opposite sides of the stirrer and a barrier (16) that separates the opposed cavities. Magnetized magnetic material (14) is disposed in the pair of opposed cavities to provide a magnetic flux axis for the stirrer. The magnetic material is so magnetized and disposed in the pair of separated opposed cavities that the magnetized magnetic material disposed in one of the pair of separated opposed cavities is magnetically attracted to the magnetized magnetic material disposed in the other of the pair of separated opposed cavities to thereby hold the magnetized magnetic material within the pair of separated opposed cavities.
