FAQ

What is a neodymium magnet?

A neodymium magnet is a type of rare-earth magnet that is made from an alloy of neodymium, iron, and boron to form the Nd2Fe14B tetragonal crystalline structure. It is the strongest type of permanent magnet commercially available.

How strong are neodymium magnets?

Neodymium magnets are extremely strong for their size. They can lift thousands of times their own weight. The exact strength depends on the grade of the magnet, which can vary based on the manufacturing process.

What are the grades of neodymium magnets?

Neodymium magnets come in different grades, such as N35, N42, N52, etc. These grades indicate the strength of the magnet. The higher the number, the stronger the magnet. Grades may also include letters after the number indicating temperature resistance.

Can neodymium magnets be demagnetized?

Yes, like all permanent magnets, neodymium magnets can be demagnetized if exposed to high temperatures (above their Curie temperature), strong demagnetizing magnetic fields, or if they are physically damaged.

Are neodymium magnets dangerous?

Neodymium magnets can be dangerous if not handled properly due to their strong magnetic force. They can snap together with great speed, potentially causing injuries or damaging the magnets. Small magnets also pose a swallowing hazard, which can be life-threatening.

How do I separate two neodymium magnets?

Separating neodymium magnets, especially strong ones, can be challenging. It's often recommended to slide them apart rather than trying to pull them directly apart. Using a piece of plastic or wood as a lever can also help. Always wear protective gloves to avoid pinching.

Can neodymium magnets affect electronic devices?

Yes, due to their strong magnetic fields, neodymium magnets can affect or damage sensitive electronic devices, such as smartphones, magnetic storage media like hard drives, and credit cards. Keep them at a safe distance from such devices.

How long do neodymium magnets last?

Neodymium magnets can last for decades if they are kept in optimal conditions, not exposed to high temperatures, strong external magnetic fields, or physical damage.

Can neodymium magnets be cut or drilled?

Neodymium magnets are very hard and brittle, making them difficult to cut or drill. Doing so requires special tools and techniques, and it should be done with caution to avoid cracking or shattering the magnet, as well as to protect from potentially hazardous dust.

How are neodymium magnets made?

Neodymium magnets are manufactured through a complex process that includes melting the raw materials (neodymium, iron, and boron), casting them into ingots, pulverizing the ingots into powder, pressing the powder in a magnetic field to align the particles, sintering the pressed compact to fuse the particles, and then machining and coating the magnets to protect them from corrosion.
