Product Description

Some mesmerizing arrangements can be achieved with a few of these ring magnets and a wooden dowel, or even a pencil in a pinch. If a copper pipe is threaded through several of the magnets with poles opposing one-another, they will support each other, while slowly sliding down the pipe. They can also be sandwiched between two washers threaded with a ziptie to secure a magnet to a workstation or tool.

It should be noted that the ring shape of these magnets makes them particularly vulnerable to cracking upon impact with other magnets or with ferromagnetic materials (most likely steel).

Nickel Plating: The standard coating for neodymium magnets is nickel. A coating is necessary because the combination of metals that makes up Neodymium magnets corrodes quickly when exposed to air. Some of our magnets are triple coated with Nickel Copper Nickel (NiCuNi) for extra durability.

NdFeB: This specification describes the composition of the magnet, Neodymium-Iron-Boron, to differentiate between magnet types and facilitate further research if necessary.

Grade: The N rating of a magnet is the way those who deal with magnets on a regular basis denote the strength of a particular magnetic material regardless of its shape. The pull force takes into account the geometry of the magnet as well

Maximum Operating Temperature: NdFeB magnets begin to act unpredictably at temperatures above 80°C (176°F). They will lose their (permanent) magnetic properties at around 200°C.
