Magnetic Product Description:

This neodymium magnetic block has a length of 20mm, width of 20mm and a height of 3mm. It has a pull force of 5.14 kilos. It is identified by the AMF magnet part number B-W20H3L20-N45.

Uses for our rare earth block magnets:

Unlike disc, ring and rectangular-shaped magnets that can be found in many commercial and retail products, Cube magnets are most commonly found in workshops. They are used to hold and brace steel angles for metal fabrication purposes. Cuboid style Neodymium magnets have higher holding ability than their lower height rectangular relatives.
The block shape has a higher intensity magnetic field that is generated from the greater volume of magnetic material between the positive and negative poles. For secure hold of metallic angles with similar dimensions, or placement inside ferrous square tubing, cube magnets are highly suitable.
Alternatively, for home, office whiteboard and general holding applications, these 20mm wide N45 Grade neo blocks are relatively easy to handle. The block shape facilitates easy repositioning around a flat surface with your fingers while stacking the block magnets in units of two produces even more magnetic grip and also makes them easier to relocate.
