Magnetic Stirrer/ Plate Stirring Water from Level 1 to 10.

The magnetic stirrer is one of my favorite pieces of lab equipment. All told it’s just a motor spinning a magnet under the top of a hot plate. By putting a magnetic stir bar on the top of the stir plate they begin to move in tandem. If the magnetic stir bar is in a liquid it will form a nice vortex and mix the liquid. Although I’m using a smaller magnetic stirrer, the effect is quite dramatic with the vortex funnel quickly reaching down to the Stirbar. After that it starts mixing air bubbles with the water. The water rises in the beaker on the stir plate as the water is spun around the beaker.
