Rare Earth Magnets

We offer a broad range of metric sizes (mm) for the science and engineering researcher. For the general public we offer a limited range of magnets in inch (American) units.

Click on the links/images for pricing and specifications including: magnetic field strengths at the surface, 0.1mm, 1mm, 10mm & 100mm above the magnets and holding/repelling force values in grams, Newtons and pounds.

Disk, square, rectangle and cylinder magnets are axially magnetized, i.e. through the flat/largest surfaces.

• All Nd magnets are made to ISO standards: 9001, 14001, 16949
• All N42 magnets are 13000 +/- 200 Gauss
• Flux density variation is ~+/- 8%

Note: Although these magnets are not marked north/south you can align them in the same direction with either a compass or magnaprobe.

Neodymium rare earth magnets are the strongest permanent magnets by weight and come in many grades; we carry N42 (13,000 Gauss) which is a good tradeoff of strength vs price for both educational & industrial applications.

Custom magnets, strengths (N40-N52) and max. temperatures (up to 180C) are available with a minimum order of $125. Send us your specifications & drawings (jpg or PDF) so we can quote you.

North/south poles are through the flat surfaces of disks, rectangles, rings and cylinders. Other axes of magnetization are available on special order. Indicate this clearly on your drawing if needed.

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.
