A magnetic stirrer is a device that stirs chemical solutions by using electromagnetic force. A magnetic stirring bar is inserted into the flask containing the solution, which is then placed over a magnetic stirrer’s hot plate. The oscillating electromagnetic field created beneath the vessel drives the rotatory motion of the stirring bar.
