NdFeb Rectangle (Block/Bar) Magnets

We have put all the NdFeB (neodymium iron boron) block magnets in one place for convenience. These magnets range from 5 to 50mm in length (~1/4 to 2") and are 1, 2.5 or 5mm thick. This shape is particularly useful for holding down materials that are thin sheets or for signage.

Our list of Neodymium Rectangle Magnet Technical Specifications includes holding forces, field strengths and size tolerances.
