Size - OD: 100mm(3.95"), ID: 60mm(2.36"), Thickness: 20mm(0.79"). With Grade 10 magnetic strength, these large magnets provide robust magnetic adhesion, ensuring they stay firmly attached to any metal surface without slipping. - 【Strength & Durability】Large Ring Ferrite circle magnets with Hole has high demagnetization resistance, corrosion resistance and oxidation resistance. High-quality materials determine the quality of magnets. The Round Circle Magnets are highly resistant to demagnetization, corrosion, making them suitable for use in challenging environments without the need for additional protective coatings. - 【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. - 【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. - 【ECONOMICAL】Compared with NdFeB magnets, this large ring ferrite magnets have no advantages in magnetic force, but magnets of the same size (compared with NdFeB magnets) sell for only a small part. The round circle magnets with hole will be packed by original AOMAG trademark package.
