If you use a lab-quality stir-plate, be sure to check what type of magnet is used inside. A neodymium magnet is the strongest type of permanent magnet, and typically works best with these strong Stir Bars. A ceramic or Alnico magnet inside the stir-plate is much weaker than a neodymium magnet. While it will still work with the neodymium stir bars shown here, it is possible to demagnetize the ceramic or Alnico magnet inside the stir-plate.

PTFE. High magnetic strength and long life due to Alnico V magnetic cores, fully encapsulated with high-grade PTFE. Strict quality control ensures the magnetic strength, position of the magnetic core, surface quality, crack resistance, and uniform thickness of the PTFE coating. Magnetic Stirrer Bar Retriever Egg Magnetic Stir Bars
Maximum operating temperature 270 °C. provides the right magnetic stirring bar for virtually any application. Rough vessel surfaces or abrasive sediments can quickly deteriorate the PTFE coating and thus shorten the life of stirring bars. This can be prevented by using reduced contact surface (e.g., with pivot ring) stirring bars.
Magnetic stirring rods that have a smaller contact surface (e.g. with center ring) provide relief. Storage conditions: Magnetic stirring rods with an Alnico V-magnet core must be stored in an orderly fashion, in order to prevent demagnification. Do not drop magnetic stirring rods onto hard surfaces, such as steel. PTFE Magnetic Stir Bar Retriever Scientific Experiments Retriever
