The 18mm countersunk magnet ring (18x5x5mm) is made from high-quality neodymium material, offering strong and stable magnetic force. Its inner hole design features a countersunk hole, allowing direct screw mounting for easy and secure installation that is unlikely to loosen....
The magnetic flux density of 18 mm neodymium magnets is mainly affected by their grade (such as N35, N42, N54) and volume. As the grade of the magnet increases, so does the magnetic flux density....
