| There are several [[types]] of agitators with the most common are the "straight-vane" and "dual-action." The "straight-vane" is a one-part agitator with bottom and side fins that usually turns back and forth. The Dual-action is a two-part agitator that has bottom washer fins that moves back and forth and a spiral top that [[rotates]] clockwise to help guide the clothes to the bottom washer fins. | | There are several [[types]] of agitators with the most common are the "straight-vane" and "dual-action."

| This is a device formed by a little metallic bar (called the agitation bar) which is normally covered by a plastic layer, and by a sheet that has underneath it a rotatory [[magnet]] or a series of [[Electromagnetism|electromagnets]] arranged in a [[circular]] [[form]] to [[create]] a magnetic rotatory field. It is very common that the sheet has an arrangement of [[electric]] [[resistance]]s that can [[heat]] some [[chemical]] solutions. | | This is a device formed by a little metallic bar (called the agitation bar) which is normally covered by a plastic layer, and by a sheet that has underneath it a rotatory [[magnet]] or a series of [[Electromagnetism|electromagnets]] arranged in a [[circular]] [[form]] to [[create]] a magnetic rotatory field.

− | Thus, during the operation of a typical magnetic agitator, the magnetic agitator bar is moved inside a container that can be a flask or a glass with some [[liquid]] inside that can be agitated. The container must be placed on the sheet, so that the [[magnetic]] field [[influences]] the agitation bar and makes it [[rotate]]. This allows it to mix different substances at high [[speeds]].[http://en.wikipedia.org/wiki/Agitation_%28action%29] | + | Thus, during the operation of a typical magnetic agitator, the magnetic agitator bar is moved inside a container that can be a flask or a glass with some [[liquid]] inside that can be agitated.
