Countersink Neodymium Ring Magnet, 30mm diameter x 5mm thick (1.38" x 0.2")

These 35mm (1.38") cylinder Neodymium ring magnets are perfect for various magnetic experiments or any other project that requires Neodymium magnets. Even better, they have a hole in the center to allow you to screw them wherever you want, and so it allows you to use it for multiple applications, especially those where you need to fix the magnet to a surface. Install them to a door to have it stay open (or closed), screw it to a wall or shelf to hold iron-made tools, etc. The limit is your imagination!

Be careful when handling large magnets as Neodymium is a brittle material and will break if magnets are dropped or snapped together.

Given the manufacturing methods required to produce such a big magnet, it’s considered normal that small esthetical imperfections be visible in the plating of big size magnets. Those small imperfections, such as little bumps or scratches do not affect in any way the performance of the magnet.
