Why Choose an N50 Block Magnet?

N50 is a high neodymium grade that provides strong magnetic performance from a very compact magnet. The flat pole faces help create reliable contact with clean, flat ferrous surfaces, making this magnet useful in commercial, industrial, technical and hobby applications.

Important: Pull force is measured under ideal test conditions. Actual holding strength may be reduced by air gaps, paint, rust, uneven surfaces, thin steel or sideways loading.
