Neodymium Bar, Block & Cube Magnets
Rare-Earth Neodymium Bar & Block Magnets
Neodymium bar, block and cube magnets are incredibly powerful for their size, with an approximate pull strength of up to 300 lbs. Neodymium magnets are the strongest permanent, rare-earth magnets commercially available today with magnetic properties that far exceed other permanent magnet materials. Their high magnetic strength, resistance to demagnetization, low cost and versatility make them the ideal choice for applications ranging from industrial and technical use to personal projects.
Neodymium Magnets in Rectangular, Square & Cube Shapes
We stock basic geometric shapes in various thicknesses and premium grades ranging from N30 to N52. Finishing options include uncoated or with a triple-coated (Ni-Cu-Ni) shiny nickel finish for optimal protection against corrosion. Not all of our magnets are shown on this website, please contact us today if you don't see what you are looking for.

Neodymium Bar, Block & Cube Magnet Features & Characteristics
Approximate Pull Info:
The approximate pull info listed is for reference only. These values are calculated under the assumption that the magnet will be attached to a flat, ground 1/2" thick mild steel plate. Coatings, rust, rough surfaces, and certain environmental conditions can significantly reduce the pull force. Please be sure to test the actual pull in your actual application. For critical applications, it is suggested that the pull be de-rated by a factor of 2 or more, depending on the severity of a potential failure.
Our neodymium discs are sintered for optimal magnetic strength and axially magnetized (the magnetism direction is along the axis of the magnet from the north to the south poles). Common finishing options include uncoated, nickel (Ni-Cu-Ni) and gold (Ni-Cu-Ni-Au) plated coatings.
Standard Dimensional Tolerances for NdFeB Bar, Block & Cube Magnets
Here are the standard tolerances for Rare Earth Magnets (SmCo & NdFeB) based on the following dimensions:
- +/- 0.004” on length & width dimensions ranging from 0.040” to 1.000”.
- +/- 0.008” on length & width dimensions ranging from 1.001” to 2.000”.
- +/- 0.012” on length & width dimensions ranging from 2.001” to 3.000”.
*Tolerance on thickness is +/-0.004” regardless of size.
Neodymium Block & Bar Magnet Applications
Neodymium block, bar and cube magnets are useful for multiple applications. From creative crafting & DIY projects to exhibition displays, furniture making, packaging, school classroom décor, home and office organizing, medical, science equipment and much more. They are also used for various design & engineering and manufacturing applications where small sized, maximum strength magnets are required. Visit our applications page to learn more.
