A magnetic disc is a circular magnet that has a diameter greater than its depth.
If the depth of the magnetic disc is greater than the diameter, it is then classed as a cylinder bar magnet.For more information on cylinder bar magnets see the page: What is a cylinder bar magnet?
The shape and large range of magnetic disc sizes available make it a very versatile magnet. Magnetic discs are often used as fridge magnets, computer memory and speakers.For information on how a disc magnet works, see the page: How does a magnet work?
Magnetic discs come in four forms: basic, planning, ring and countersunk.
