Can a magnetic stirrer be used in cooking?
Magnets are used in countless modern “stirring” applications where contamination is a concern. The Solution: EAM first designed a multi-pole ceramic ring magnet that would be cost effective, however also provide enough coupling strength to drive the stirrer through the various food products.
What are stir bars used for?
A stir bar consists of a magnetic bar used to agitate a liquid mixture or solution (Figure 6.6). Because the glass does not affect a magnetic field significantly, and most of the chemical reactions are performed in glass vials or beakers, stirring bars function adequately in glassware commonly used in laboratories.
