Magnetic Stirrer Making

Magnetic stirrer is a mixing device which is commonly used in laboratories. For mixing different types of liquid samples.It consist on rotating magnet that creat rotating(adjustable) magnatic field to move stirring bar or spin bar(cylindrical magnet having narth pole and south pole) in soloution. The movement of this bar mix soloution very quickly. The speed of stirring is controlled by the user according to specific sample that's being stirred.Use glass beaker to prevent the interference of magnatic field.

The making procedure of this device is very simple ,you can make easily at home by following few easy steps.
● design body structure of device. we use wooden boards to build of device.



●Use silver plate in the stirring area to prevent the interference of magnetic field.

●To conteol the speed of stirring  we use PWM speed controller(dc motor speed controller)

●To create rotation magnatic field attach a piece of magnet on the one side of wooden bar.
●Connect the wooden bar to dc motor.

●Connect the Dc motor middle of stirring area.
