4PCS Large Ferrite Ring Magnet - Grade 10 Big Magnets Heavy Duty, OD60mm x ID32mm x 10mm, Ceramic Circular Magnets for Industry Science, School,Crafts and Hobbies

【Size】 These are 4pcs 60MM X 32MM X 10MM (OD2.35" x ID1.25" x 0.4'')these large magnets provide robust magnetic adhesion, ensuring they stay firmly attached to any metal surface without slipping 【Workship】Ceramic magnets made by molding process, having more rounded edge. In addition, these ring ferrites are similar in magnetism to neodymium rare earth magnets and cheaper than neodymium rare earth magnets. 【Multiple Uses】These Big round magnets are widely used as classroom magnets, refrigerator magnets, industrial magnets, whiteboard magnets, motors and generators, sensors, speaker magnets, scientific magnets and DIY magnets. With the ability to meet the needs of all your magnetic projects, the magnetic ring will be a reliable tool in your daily life. 【Durability and Stability】 Ferrite Round Magnets have High resistance to demagnetization, corrosion and oxidation. It can exists forver under 180°Temperature. 【Efficient Storage Solution】Use the large ring magnets to organize and secure metal tools and other items, saving space and reducing clutter in your workspace. Round Ceramic magnets made by molding process have more rounded edges than those cut by cutting, and are made of rare earth permanent magnetic materials mixed with other metal materials.
