**Magnet size is prior to rubber coating
Most Ring Magnets are axially magnetised: North and south poles are located on the flat circular surfaces (“top and bottom”). The few diametrically magnetised ring magnets with poles “left and right” are specifically marked.
Applications for neodymium ring magnets
Two ring magnets demonstrate “magnetic levitation” – floating caused by magnetism – in an easy and impressive way. You need two axially magnetised neodymium ring magnets and a pen on which both magnets are pushed together with the same poles. If you hold the pen vertically, the resulting repulsion makes the top magnet float.
With diametrically magnetised ring magnets you can build sculptures. You can also combine them with other shapes, such as neodymium rod magnets. Browse through our customers’ applications to find out how versatile ring magnets are. Extra Small Sewing Magnets w/ Circular Plastic Cover 10mm

Protective coating of nickel or leaf gilding
Rubber coating of pot magnets is considered useful when using sensitive surfaces like glass and plastics, or highly finished vehicular surfaces. Rubber coating is also useful to prevent corrosion in marine, aquatic or external environments, as well as in areas where metal strike presents a risk to the magnet. Metal strike situations are more likely in mechanical environments related to motors and machinery.
Rubber coated pot magnets are often placed to create a fixing or hanging point. The rubber coating provides for superior slide resistance due to greater friction between the rubber and steel surface to which the magnet is bonded. Manufacturers and industrial designers use rubber coated pot magnets for holding and fastening.
Products and devices held together with rubber coated pots allow you to easily uncouple the magnet at pre-determined pressure points for regular cleaning or servicing.
