Additionally, how are magnetic stirrers made? Normally, the magnetic stirrer consists of a magnetic needle that is immersed in the container carrying the mixture of nanomaterial and the base fluid and that rotates due to the rotating magnetic field generated with the help of electromagnets present inside the stirrer instrument.

How does a magnetic hot plate work?

Underneath the platform, a rotating magnetic field is created by either a rotating magnet or by running electric current through stationary electromagnets. The magnetic stir bar interacts with the rotating magnetic field and is always trying to align itself with the orientation of the field.

How does a magnetic stirrer hot plate work?

A stir bar magnet is placed inside a container, immersed in the fluid. A separate magnet is placed underneath the container so that it attracts to the stir bar magnet. The lower magnet is usually attached to a motor that spins it. If the magnets are close enough, the stir bar magnet spins inside the container.

What are magnetic stirrers 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.

What can I use as a magnetic stir bar?

What is a spinbar?

Elliptical (Egg-Shaped) Spinbar® Magnetic Stirring Bars

SP Bel-Art. These egg-shaped stirring bars are designed especially for use in round-bottom vessels as they spin unrestricted by the vessel contour.

What is a Teflon stir bar?

Scientists have discovered that stir bars made of PTFE, more commonly known as Teflon, can introduce errors into a standard lab reaction used to manipulate the properties of carbon or boron-nitride nanotubes. Stir bars are pellet-like rods of ferromagnetic metal covered in PTFE that sit in the bottom of a beaker.

What size magnetic stir bar should I use?

The Size of the Internal Drive Magnet

The size of the magnet inside the stirrer, which may be referred to as the drive magnet, is of great importance when choosing a stir bar size. The length of the bar should be about equal to the magnet size to avoid spinout.
