Large Ceramic Ring Magnet,Industrial Grade 8 Ferrite Ring Magnets with Hole for Science Experiment-OD100mmxID60mmx15mm

Large Ceramic Ring Magnet,Industrial Grade 8 Ferrite Ring Magnets with Hole for Science Experiment-OD100mmxID60mmx15mm

• The Best Ceramic Ring Magnets Made under ISO 9001 Quality Systems.Grade 8,which is Stronger than Grade 5.
• 【SIZE】 The outside diameter is 3.9 inch (100 mm), the internal diameter is 2.36 inch (60 mm), and the thickness is 0.59 inch (15 mm).
• 【PERFORMANCE】 The ring magnets with hole is made by ceramic process. Circle hole magnets are hard and brittle material, have good temperature resistance, anti-corrosion and rust prevention, cheapness and moderate performance.
• 【BEST PRICE & QUALITY】 Compared to more expensive rare earth or neodymium magnets, these circle donut magnets offer much better value for all your magnetic project needs.Great ring magnets for You DIY Projects!
• 【WARNING】The ferrite ring magnets is very fragile, it is forbidden to collide with other metal objects (including another magnet), so be careful when you are trying separate them!
