What is the use of magnetic stirrer in laboratory?
A magnetic stirrer is a device widely used in laboratories and consists of a rotating magnet or a stationary electromagnet that creates a rotating magnetic field. This device is used to make a stir bar, immerse in a liquid, quickly spin, or stirring or mixing a solution, for example.

How does a magnetic stirrer work?
Magnetic stirrers use a rotating magnetic field to move a stir bar around in liquid samples. The movement of this stir bar mixes the sample thoroughly with rapid movement and agitation. The speed of the magnetic field is controlled by the user, so it can be customized to the specific sample that’s being stirred.
What are the magnetic stirrers called?
A small magnetic bar coated in Teflon or glass, commonly referred to as a flea or stir bar, is submerged in the vessel containing the materials to be stirred.
How do you use a magnetic stirrer in a lab?
To use the magnetic stirrer: Turn on the magnetic stirrer by flipping the power switch on (–), then rotating the left knob in a clockwise direction. 3. The farther you rotate the knob, the faster it will spin to stir your solution. You can control the stirring speed between about 120 and 1400 rpm.
What is the function of a magnet?
Magnets do the following things: Attract certain materials, such as iron, nickel, cobalt, certain steels and other alloys. Exert an attractive or repulsive force on other magnets (opposite poles attract, like poles repel).

What is magnetic stirrer in microbiology?
With the use of a magnetic field, a magnetic stirrer rotates a stir bar. The rod-shaped magnet is placed in a beaker or bottle containing liquids. By rotating the stir bar, the liquid is properly mixed. A magnetic stirrer can, among other things, be used to prepare medium to culture microbes.
What is electromagnetic stirrer?
Electromagnetic stirring (EMS) is the process by which a high level of stirring efficiency can be achieved through interaction between the magnetic field from the static induction coil and the electrically conducting metal bath.
What is the use of magnetic stirrer with hot plate?
A standard piece of laboratory equipment, the hot plate stirrer / hot plate magnetic stirrer keeps liquids circulating as they are heated for a faster, more even reaction.
What are magnetic stir bars made of?
Many stir bars are made with ceramic or Alnico magnets. Ceramic magnets are inexpensive and common, but not nearly as strong as a neodymium magnet. They have only about 8-10% of the pull force. Alnico magnets are made from aluminum, nickel and cobalt.
