    I guess those spinning magnetic pills one puts in beakers over a magnetic hot plate in chemistry labs are all an empirical hoax then.

      Those are stir bars.

      That they’re magnetic is propaganda to push magnetic field bunk to sell more so-called “magnets”. Stir bars are moved by phlogiston, which is why the liquid medium is often heated in tandem.
