Magnetic Product Description:

This neodymium magnetic ring has an outer diameter of 5mm, an inner diameter of 2.5mm and the height of 4mm.  It is identified by the AMF magnet part number R-OD5H4ID2.5-N52.

Uses for our rare earth ring magnets:

Although petite in size, this Neodymium ring magnet is made of powerful N52 grade rare earth material. N52 is the highest grade of Neodymium commercially available, it provides a stronger magnetic power than a magnet of the same dimensions in a lower grade such as N35 at the other end of the scale.
Small ring magnets are popular with makers of all kinds as the center hole provides an easy method of securing the magnet in place. Woodworkers utilise the hole to achieve greater purchase with glue to hold the magnet in place as a magnetic latch or closure. Knitters, felt makers and stitchers of all varieties enjoy the ability to sew through the centre of the magnet to create a magnetic means of displaying their work or as an alternative fastening system. Ring magnets really are highly adaptable as they can be attached with wire, string, cord or even slotted onto a rigid element like a bolt.
