Ø40×20×8 mm Countersunk Neodymium Magnet

40 mm Diameter Ring Neodymium Magnet

This standard-hole 40×20×8 mm neodymium magnet has an inner diameter of 20 mm and is considered a custom-sized product. This NdFeB neodymium magnet is a permanent rare-earth magnet and is known as the most powerful type of magnet available. Its 8 mm thickness provides a very strong magnetic pull. Therefore, keep it away from children and electronic devices. Avoid letting magnets collide with each other, as they can break.

Neodymium magnets are extremely strong but also brittle. If two powerful magnets collide, they are very likely to crack or shatter. When separating magnets, slide them apart rather than pulling directly. Be careful not to pinch your fingers. As the strongest magnets found in nature, these neodymium magnets retain their magnetic strength for a long time. Do not expose them to high temperatures, as temperatures above 80°C can cause neodymium magnets to lose their magnetic properties.

Information: Our magnets come with Gauss certification, which can be provided upon request for an additional fee. Our company offers Gauss measurement and certification services for all magnetic systems. Magneteksan manufactures magnetic equipment and magnets for many industries, including defense, automotive, public institutions, food companies, recycling, and mining.
