This neodymium cylinder has a diameter of 11mm and a height of 30mm. It has a magnetic flux reading of 6197 Gauss and a pull force of 5.1kgs against 3mm mild steel. It is identified by the AMF magnet part number 21021.
Cylinder shaped Neodymium magnets can operate inside a thin tubular unit made of plastic or similar material that allows the magnet to slide in an unrestricted linear direction, involving either a repelling or attracting force. As metal or other magnets interact with the cylinders field and relative position, the information can help to determine important positioning data. This can be used to identify and rectify position or direction of movement, in a vehicle or vessel for instance, to maximise performance or enhance its safety features. Cylinder magnets with their narrow but deep magnetic field are found in many of the reliable and accurate modern-day safety devices developed by Automotive Manufacturers worldwide.

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
