Neodymium Disc Magnet - 10mm Dia X 1mm Thick - Pack Of 20

A Neodymium magnet is a type of permanent magnet made from an alloy of Neodymium, Iron, and Boron (NdFeB). They are known as 'rare earth' magnets and are among the strongest types of permanent magnets available.

Each magnet can support a steel weight of up to 0.51kg vertically when in flush contact with a mild steel surface. This is known as the 'pull force' and can vary based on conditions.

It means the magnets are coated with three layers (nickel, copper, nickel) to protect them from rust and corrosion, extending their lifespan and maintaining their appearance.

It is recommended to keep strong magnets like Neodymium away from sensitive electronic devices, credit cards, magnetic media, and medical devices like pacemakers due to their strong magnetic fields.

Yes, if your refrigerator door is made of steel. The magnets will adhere to any ferrous metal surface.

Store them in a cool, dry place, separated by non-magnetic material (like cardboard or plastic) or with their opposite poles facing each other if stored in strips, to prevent them from snapping together. Avoid storing them near heat sources.

Forcefully snapping strong magnets together can cause them to chip, break, or even shatter due to the immense force. Handle them with care and control.

Ensure the steel surface is clean, flat, and free from paint or rust. Check for any air gap between the magnet and the surface. Verify the object being attracted is sufficiently ferrous.

Ensure magnets are stored correctly, away from high temperatures and strong opposing magnetic fields. Verify the coating is intact and not significantly corroded.

Neodymium magnets can be brittle. Handle them carefully, especially when bringing them close to other magnets or metal surfaces, to avoid impact. Broken magnets can still be functional but may have sharp edges.
