==Description==
An '''agitator''' is a device or [[mechanism]] to put something into [[motion]] by shaking or stirring.
==Washing machine agitator==
In a top load [http://en.wikipedia.org/wiki/Washing_machine washing machine] the agitator [[projects]] from the bottom of the wash basket and [[creates]] the wash [[action]] by rotating back and forth, rolling garments from the top of the load, down to the bottom, then back up again and due to that it seems so.
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.
The [[modern]] agitator, which is the [[dual]] [[action]], was first made in [http://en.wikipedia.org/wiki/Kenmore Kenmore] [http://en.wikipedia.org/wiki/Washing_machine washing machines] in the [http://en.wikipedia.org/wiki/1980's 1980s] to present. These agitators are known by Kenmore as dual-rollover and triple-rollover [[action]] agitators.
==Magnetic agitator==
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.
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]
