6.4mm x 3mm x 5.5mm Neodymium Diametrically Magnetized Ring Magnet N44H Strong Rare Earth Ring Magnets (10 Pack)

6.4mm od x 3mm id x 5.5mm thick N44H Diametrically Magnetized Ring Magnet Strong Neodymium Ring Magnets Nickel Coated Diametrically Magnetized Donut Magnet

If you lay a diametrically magnetised ring magnet flat in front of you, the north pole is located, for instance, on the left half and the south pole on the right half. Consequently, these ring magnets stick together sideways, similar to the way you place backgammon pieces.

Please note that all neodymium rare earth magnets are fragile and require caution when installing to prevent shattering the magnet due to their brittle nature, and to avoid injury due to pinching.

Neodymium magnets are perfect for use in dry indoor areas. Diametrically magnetised magnets are often utilised in sensor technology or for magnetic couplings or switches.
