8MM Round Neodymium Magnets (10Pcs)

Notes:
A neodymium magnet (also known as NdFeB, NIB or Neo magnet), the most widely used type of rare-earth magnet, is a permanent magnet made from an alloy of neodymium, iron and boron to form the Nd2Fe14B tetragonal crystalline structure. Developed in 1982 by General Motors and Sumitomo Special Metals, neodymium magnets are the strongest type of permanent magnet commercially available. They have replaced other types of magnet in the many applications in modern products that require strong permanent magnets, such as motors in cordless tools, hard disk drives and magnetic fasteners.

All Rare-Earth magnets are fragile /brittle and can break easily. These magnets will become demagnetized when exposed to high heat. These magnets are powerful and can accelerate at high speeds toward each other and toward ferrous material. When these magnets come together quickly, they can shatter and break.These magnets can also pinch strongly if allowed to come together against the skin. Do not let the Magnets snap together. This will most likely cause the magnets to break.

Rare-earth magnets have strong magnetic fields that can damage electronic equipment and magnetic data storage media. You should keep these magnets away from electronic equipment, computer discs, credit cards, video tapes, and other magnetic media.

Rare-earth magnets should not be burned. These magnets can ignite and burn at high intensity. These magnets should not be drilled or machined. Drilling and machining may produce metal powder which is flamable and may cause high heat to develop resulting in ignition. The magnets may shatter and break when drilled or machined.

Rare-earth magnets are primarily composed of neodymium, dysprosium, samarium, iron, and boron. The chemical, physical and toxicological properties of neodymium, samarium and dysprosium have not been thoroughly investigated and recorded. Rare-earth magnets should not be used in contact with food or ingestible liquids. Rare-earth magnets should not be used in long term contact with the skin. The current Material Safety Data Sheets (MSDS) should be consulted to obtain current procedures for handling or working with these substances in a safe manner.
