Magnets are not toys! Keep magnets out of the reach of children.

bruises
- Large magnets have a very strong attraction. If handled carelessly, you can pinch your fingers or skin between two magnets. This can lead to bruising and contusions at the affected areas.
- Very large magnets can cause bone fractures due to their force.
Wear thick protective gloves when handling larger magnets.
pacemaker
Magnets can affect the function of pacemakers and implanted defibrillators.
- A pacemaker can be switched into test mode and cause discomfort.
- A defibrillator may no longer work.
- If you wear such devices, keep a sufficient distance from magnets.
- Warn wearers of such devices not to approach magnets.
Heavy objects
Excessive or sudden loads, fatigue, and material defects can cause a magnet or magnetic hook to detach from its base. Falling objects can cause serious injuries.
- The specified holding force is only achieved under ideal conditions. A high safety factor should be included.
- Do not use magnets in places where material failure could cause injury to persons.
Metal splinters
Neodymium magnets are brittle. If two magnets collide, they can shatter. Sharp-edged shards can be thrown meters away and injure your eyes.
- Avoid collisions between magnets.
- Wear protective goggles when handling larger magnets.
- Make sure that people around you are also protected or keep their distance.
Magnetic field
Magnets generate a strong, far-reaching magnetic field. They can damage televisions and laptops, computer hard drives, credit cards and debit cards, data storage devices, mechanical watches, hearing aids, and loudspeakers, among other things.
- Keep magnets away from all devices and objects that can be damaged by strong magnetic fields.
- Please refer to our table with recommended distances.
Flammability
When machining neodymium magnets, the drilling dust can easily ignite.
Avoid machining magnets or use suitable tools and sufficient cooling water.
Nickel allergy
Many of our magnets have coatings that contain nickel.
- Some people are allergic to contact with nickel.
- Nickel allergies can develop through constant contact with nickel-plated objects.
- Avoid permanent skin contact with nickel-coated magnets.
- Avoid using magnets if you already have a nickel allergy.
Air freight
- Only ship magnets by air freight in packaging with sufficient magnetic shielding.
- Observe the relevant regulations.
Postal delivery
- Please note our shipping tips.
- Use a generously sized box and place the magnets in the center of the package using filling material.
- Arrange the magnets in a package so that the magnetic fields neutralize each other.
- If necessary, use iron sheets to shield the magnetic field.
- Stricter rules apply to shipping by air freight: Please note the warning "Air freight".
Effect on people
According to current knowledge, magnetic fields from permanent magnets have no measurable positive or negative effects on humans. A health risk from the magnetic field of a permanent magnet is unlikely, but cannot be completely ruled out.
- For your safety, avoid constant contact with the magnets.
- Keep large magnets at least one meter away from your body.
Chipping of the coating
Most of our neodymium magnets have a thin nickel-copper-nickel coating to protect against corrosion. This coating can chip or crack due to collisions or excessive pressure. This makes the magnets more sensitive to environmental influences such as moisture and can lead to oxidation.
- Separate large magnets, especially balls, with a piece of cardboard.
- Generally avoid collisions between magnets and repeated mechanical stress (e.g. impacts).
Oxidation, corrosion, rust
Untreated neodymium magnets oxidize very quickly and disintegrate. Most of our magnets have a thin nickel-copper-nickel coating to protect against corrosion. This coating offers some protection against corrosion, but is not durable enough for continuous outdoor use.
- Only use the magnets in dry indoor areas or protect them from environmental influences.
- Avoid damaging the coating.
Temperature resistance
Neodymium magnets have a maximum operating temperature of 80 to 200 °C. Most neodymium magnets permanently lose some of their holding power at temperatures above 80 °C.
- Do not use the magnets in places where they are exposed to high heat.
- If you use an adhesive, do not cure it with hot air.
Mechanical processing
Neodymium magnets are brittle, sensitive to heat and oxidize easily.
- Drilling or sawing a magnet with unsuitable tools can cause the magnet to break.
- The resulting heat can demagnetize the magnet.
- Because of the damaged coating, the magnet will oxidize and disintegrate.
Avoid mechanical processing of magnets if you do not have the necessary machinery and experience.
