Neodymium Rare Earth Magnets
Rare earth magnets have been available since the 1970s, the first is samarium cobalt (smc0), which is always preferred for applications at high temperature (300C), but has also been largely supplanted by neodymium iron boron (NdFeB). Rare earth magnets come in all shapes and sizes, including wheels, rods, squares, rectangles, cubes and rings and many qualities.
We provide nearly almost 150 high-quality formats N42 grade rare-earth magnet mainly for pricing scientific, technical and industrial, but cheap enough that fans, artists and inventors can afford.
As the curious and inventive mind is everywhere, we also offer custom rare earth magnets for a minimum of $ 125.00 plus shipping. Send us your drawings and other information, and we will respond within 24 hours.
Rare earth disc magnets are by far the most popular type of “round” magnets and include uses such as closures for product literature binders and art portfolios to bulletin board “thumbtacks”. For simplicity, we have divided these into small disc magnets which range from 2.5 to 12.5mm in diameter (1/10 to 1/2″) and the stronger large disc magnets which cover 15-25mm in size (3/5 to 1″). Dimensions are specified as “diameter-thickness”.
Rare Earth Magnets
Rare earth rod or cylinder magnets are a subset of round magnets that are differentiated in having their height greater than or equal to their diameter and are specified as “diameter-height”. The taller versions of this style are very handy for use as stud finders and nail locators.

ring rare earth magnets, sometimes also called “donut” magnets and are, as one might imagine, the disc magnets with a hole in the center. Its dimensions are listed as “outside diameter, inside diameter thick.” Try to mount a lot of them in a pencil a simple demonstration of levitation.
Cubic rare-earth magnets can be constructed groups Halbach, drilling gun metal or wood or construction material is very expensive. By definition, all three sides of the cube are of equal length.
rare earth magnets squares have equal sides and thickness dimensions are considered undesirable side where the sides are of equal length. Applications include use in brushless motors, bicycle speedometers and fly fishing reels.
rare-earth magnets to ensure that the dimensions are listed in the “length-width-thickness” is always the length of the maximum size of three. They are convenient to use the surface signaling, or when used in pairs as a simple knife or tool rack.
