Neodymium Rare Earth Magnets

Rare earth magnets have been available since the 1970's; the first being samarium cobalt (SmC0) which is still favored for high temperature applications (300C) but have otherwise largely been supplanted by neodymium iron boron (NdFeB). Rare earth magnets come in all shapes and sizes including discs, rods, squares, rectangles, cubes and rings and in many grades.

We offer nearly nearly 150 sizes of high quality N42 grade rare earth magnets primarily for science, engineering and industry but at cheap enough prices that hobbyists, artists and inventors can also afford them.

Because curious and inventive minds are everywhere, we also offer custom rare earth magnets for as little as $125.00 plus freight. Send us your drawings and any other details and we will try to reply within 24 hours.

Neodymium Rare Earth
Disc, Cylinder and Ring Magnets

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 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.

Rare earth ring magnets, also sometimes called "donut" magnets and are, as one would guess, disc magnets with a hole in the middle. Their dimensions are listed as "outer diameter-inner diameter-thickness". Try mounting a stack of them on a pencil for a simple demonstration of levitation.

Neodymium Rare Earth
Cube, Block and Square Magnets

Rare earth cube magnets can be used to build Halbach arrays, clamp metals or wood for drilling or as very expensive building blocks. By definition, all 3 sides of a cube are equal length.

Square rare earth magnets have two sides of equal length and dimensions are specified as side-side-thickness, where sides are equal length. Their applications include use in brushless motors, bicycle speedometers and fly fishing reels.

Rare earth block magnets have dimensions listed as "length-width-thickness" with length always being the largest dimension of the three. They are convenient for use in holding up signage or when used in pairs as a simple knife or tool rack.

Safety Warning!

• Can damage computer gear & credit cards.
• Handle with care. Magnets can snap together and break skin or a finger or shatter on impact.
