This rare earth cylinder has a diameter of 4mm and a height of 5mm. It has a magnetic flux reading of 5849 Gauss and a pull force of 0.540kg. Its part number is 21055.
This tiny Neodymium Cylinder is popular with hobbyists, model makers, jewellers and costume designers. Cylinder shaped magnets are suited to recessing into surfaces where their narrow magnetic field can attract, hold and position metal items, or other similarly embedded objects, in the correct place. Unlike Discs or Block shaped magnets, the narrow projection of a cylinder's magnetic field means less chance of interference to sensitive areas nearby. This concentrated type of field translates with great benefit in detection devices, warning sensors and security systems, where field sensitivity is vital for reliable and accurate operation.

The Pull Force listed for each magnet is based on lifting 10mm thick steel from a horizontal surface. Magnets on a vertical surface (of 10mm thick steel) are generally able to hold around only 30% of the pull force listed in the product description. This is due to the effects of gravity and the lack of friction between the surface and the shiny magnet. Read More
