20x3mm Neodymium Disc Magnet N35 Grade Super Strong Rare Earth Magnet

Prototyping and Engineering Tips from Robogears

• Magnetic Door Latches: These are the ideal size for cabinet door catches. You can recess one into the door and another into the frame for a strong, "click-free" closure that stays hidden.

• Surface Preparation: If you are gluing these to a surface, ensure it is clean and dry. Use a high-strength epoxy or specialized magnetic adhesive for the best bond, as the high pull force can sometimes pull the magnet off the glue.

• Stacking for Strength: If you need a deeper magnetic reach, you can stack two or more of these discs. Stacking increases the magnetic flux density, essentially turning them into a thicker, more powerful magnet.

• Handle with Care: Neodymium is a brittle material. Avoid snapping two magnets together from a distance, as the impact can cause them to chip or shatter. Always slide them apart or use a non-magnetic separator.
