What is so special about 2mag stirring systems? The secret of the magnetic stirrers is hidden in the drive. Conventional magnetic stirrers use an electrical motor spinning a permanent magnet, thus exerting a force on the magnetic stirring bar within the stirring vessel. In 2mag motor -less magnetic stirrers, electrical motors and permanent magnets are replaced by stationary magnetic coils through which currents flow, producing a rotating electromagnetic field. A digital electronic circuit coordinates the currents supplied to the coils. It re-calculates and controls currents up to 1000 times a second.
