Neodymium Cylinder Magnet - 4mm x 20mm

Magnetic Product Description:

This rare earth cylinder has a diameter of 4mm and a height of 20mm. It has a magnetic flux reading of 6269 Gauss and a pull force of 0.630kg. Its part number is 21051.


Uses for our rare earth cylinder magnets:

This Neodymium Cylinder magnet has a small diameter creating a narrow magnetic field, concentrated by the length of the magnet to create a penetrating field through the polarised flat faces. This type of magnetic field means cylinders are not usually chosen for weight bearing or holding applications. Metal detection and removal applications are well suited to magnets such as these, utilising the concentrated depth of magnetic field to locate ferrous materials such as steel studs beneath a substrate. These are also a great magnet to have on hand for keeping your workspace free of metal filings and stray screws. Popular with those working in metal working industries such as Toolmakers, Tradespeople and Steel-fixers who use cylinder magnets to keep their work areas uncontaminated and to product quality at the highest standard possible.
