A magnetic stirrer consists of a small bar magnet (or stir bar), normally coated in plastic, and a stand or plate containing a rotating magnet or stationary electromagnets creating a rotating magnetic field. The bar magnet is placed in a beaker or flask containing a liquid to be stirred. The vessel is set on top of the stand, and the rapidly rotating magnetic field causes the bar magnet to rotate. The liquid is stirred.
