The diameter size of these magnets are smaller than height size,they are referred to as cylinder(rod) magnets.Its express way is the same as disc neodymium magnets. Due to extra strong magnetic force, cylinder(rod) magnets of rare earth neodymium have wide application range. The smallest diameter of cylinder neodymium magnets is 1 mm . The longest neodymium cylinder(rod) magnets we made is 100 mm long, which is the magnetized direction. We list out some sizes of which are regularly supplied. Any sizes can be customized without tooling fee.
