Abstract
Magnetic stir bar having at least one permanent magnet to spin the magnetic stir bar when the magnetic stir bar is subjected to a rotating magnetic field. The magnetic stir bar has a chamber to store a product within the magnetic stir bar. The magnetic stir bar has a closed configuration in which the chamber is closed and an open configuration in which the chamber is open. The magnetic stir bar automatically reconfigures itself from the closed configuration to the open configuration when said magnetic stir bar is spun at or above a threshold rotational speed.
