Magnet Safety
Swallowing
Children can swallow small magnets. If several magnets are swallowed, they could get stuck in the intestine and cause serious health problems. Magnets should not be used as toys.
Handling
Large magnets have very strong attractive force. Improper handling could cause jamming of fingers or skin in between magnets, leading to injury or bruising. Stronger magnets can even cause bone fractures. Wear correct safety equipment when handling larger magnets.
Pacemaker
Magnets can affect the functioning of pacemakers and implanted heart defibrillators. If you use one of these devices, keep at least 1 meter away from magnets and warn others who may be at risk.
Electrical Conductivity
Magnets conduct electricity. Children may insert magnets into outlets, risking electric shock. Never let children play with magnets.
Corrosion
Uncoated Neodymium magnets can oxidize and disintegrate. Most are nickel-plated but this is not suitable for continuous outdoor use. Use indoors and avoid damaging the coating.
Heavy Objects
Magnets holding heavy objects can fail and cause injury. Pull force values are theoretical and under perfect conditions. Do not use magnets in critical safety zones.
Metal Splinters
Magnets are brittle. When they collide, they may crack and send sharp splinters flying. Wear protective eyewear and avoid collisions. Ensure people nearby do the same.
Influence on People
Magnetic fields have no proven health risk, but constant exposure is not recommended. Avoid close contact with large magnets and store them at least 1 meter away from the body.
Magnetic Field
Large magnets can damage electronics (TVs, laptops, credit cards, etc.). Keep at least 1 meter distance from sensitive devices and storage media.
Flammability
Drilling or grinding magnets can create flammable dust. Avoid machining, or use proper tools with cooling systems.
Heat Resistance
Neodymium magnets lose strength above 80°C (most grades). Avoid exposing magnets to heat beyond their rated temperature.
Nickel Allergy
Many magnets contain nickel, which can cause allergic reactions from repeated contact. Avoid skin contact if you have a known allergy.
Airfreight
Incorrectly packed magnets can interfere with aircraft instruments. Follow packaging regulations carefully to avoid delays, extra costs, or bans.
Postage
Magnets can damage nearby parcels or disrupt sorting machines. Use lots of padding, arrange magnets to neutralize their field, and shield them with sheet iron if needed.
Splintering of Coating
Nickel-coated magnets can splinter under pressure. This exposes them to moisture and corrosion. Avoid physical damage and don’t store them against cardboard.
Machining of Magnets
Neodymium magnets are brittle, sensitive to heat, and corrode easily. Drilling can cause breakage and demagnetization. Do not machine them unless professionally equipped.
