Teflon NdFeB Magnet Ring Neodymium Magnets are for applications that require low friction and high resistance to liquids and ultrasonic cleaning. Teflon also helps protect the magnet from chipping or breaking. High-performance, PTFE-coated Neodymium ring magnet – water resistant and machine washable, ideal for clothing garments and accessories.

Neodymium magnet(also know as NdFeB,NIB, or Neo magnet), the most widely used type of rare-earth magnet, is a permanent magnet made from an alloy of neodymium, iron and boron to form the Nd2Fe14B teragonal crystalline structure. These magnets are widely used in many applications in modern products, such as motors in cordless tools, computer hard drives, wind turbine generators/audio speakers/headphones, bicycle dynamos ……
These Neodymium ring magnets produce a deep enough magnetic field to attract each other through their PTFE coating and material such as fabric. Their special PTFE coating means they are completely sealed and water resistant, making them ideal for closures and clasps on clothing and accessories.
