Ring Magnet 15x4.5x3.5 mm N42 Nickel with countersink

Product information "Ring Magnet 15x4.5x3.5 mm N42 Nickel with countersink"

Ring magnets are usually magnetised axially (please see technical drawing); if you need a different way of magnetisation in most cases this won't be a standard magnet. Ring magnets with countersink are often used pairwise; then you need one ring magnet with south pole at countersink side, one magnet with north pole at countersink side. Therefore we deliver magnets with countersink in even numbers only.
