Neodymium Magnet Safety
The neodymium magnets in this product are extremely strong. They must be handled with care to avoid personal injury or damage to the magnets.
Powerful attraction forces can cause serious injury.
Neodymium magnets are more powerful than other kinds of magnets. The incredibly powerful force between magnets can often be surprising to those unfamiliar with their strength. Fingers and other body parts can be pinched between two magnets or magnets and metal objects.
Neodymium magnets are not for children.
Neodymium magnets are not toys. Children should not be allowed to handle neodymium magnets. Small magnets can pose a choking hazard. If multiple magnets are swallowed, they can attach to one another through intestine walls. This can cause a severe health risk, requiring immediate, emergency surgery if correctly diagnosed.
Neodymium magnets can affect pacemakers.
The strong magnetic fields near a neodymium magnet can affect pacemakers, ICDs and Other implanted medical devices. Many of these devices are made with a feature that deactivates it with a magnetic field. Therefore, care must be taken to avoid inadvertently deactivating such devices.
Neodymium magnets are brittle and fragile.
Neodymium magnets are made of a hard, brittle material. Despite being made of metal, and the shiny, metallic appearance of their nickel plating, they are not as durable as steel. Neodymium magnets can peel, chip, crack or shatter if allowed to slam together.
Magnets can affect magnetic media.
The strong magnetic fields near neodymium magnets can damage magnetic media such as floppy disks, credit cards, magnetic I.D. cards, cassette tapes, video tapes or other such devices. They can also damage televisions, VCRs, computer monitors and CRT displays. Avoid placing neodymium magnets near electronic appliances.
Those with nickel allergies should avoid prolonged contact with magnets.
A small percentage of people have a nickel allergy, where an allergic reaction can cause redness and a skin rash. Those with nickel allergies should avoid directly handling nickel plated neodymium magnets.
Strong magnetic fields can interfere with compasses and navigation.
IATA (International Air Transport Association) and US Federal rules and regulations cover shipping magnets by air and ground delivery. Magnetic fields can influence compasses or magnetometers used in air transport. They can also affect internal compasses of smartphone and GPS devices.
