exactly what I wanted.
Needed a small strong magnet for model railway use, fitted between the rails for uncoupling action. Works 100%. Great.

This neodymium rare earth cylinder magnet measures 3 mm (D) x 10 mm (H). It has a magnetic flux reading of 6230 Gauss and a pull force of 310 grams. GRADE N38.
Specifications for cylinder magnets are given according to their height and diameter. These types of magnets have straight parallel sides, are circular in cross-section and sometimes house a hollow center or central void for sliding and lodging onto a spindle or shaft. The shape of a magnet determines how the magnetic field lines are arranged around the magnet as well as the pull strength. These cylinder magnets are particularly useful in the field of nuclear magnetic imaging and in filtration devices to remove unwanted ferrous and other contaminants from dry particle products and liquids.

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
