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.


Large magnets do have a very strong attractive force.

  • Improper handling could cause jamming of fingers or skin in between magnets. This may lead to injury and bruising.
  • Bigger and stronger magnets can cause bone fractures.
  • Wear the correct safety equipment when handling larger magnets.


Magnets could affect the functioning of pacemakers and implanted heart defibrillators.

  • A pacemaker can be affected by magnets.
  • A heart defibrillator can stop working.
  • If you use one of these devices, please keep a safe distance (at least 1 meter) from magnets.
  • Also, do warn other people you may know that have these devices to keep away from magnets.

Electrical conductivity:

Metal is used when magnets are made and conduct electricity. Individuals/Children might try to put magnets into a power outlet and can suffer from an electric shock. Don’t let children play with magnets.


Neodymium magnets that are not coated can oxidize quickly and disintegrate.
Most of our magnets are nickel-plated to protect them from corrosion. This coating does provide some protection, but it is not robust enough for continuous outdoor use.

  • Try to use Neodymium (Rare Earth) magnets inside instead of exposing them to the outside weather.
  • Avoid damaging the plating on the magnet.

Heavy Objects:

Magnets that have a too heavy load, can loosen from a surface it is attached to, which can result in serious injury when the object attached to the magnet fails to adhere to the magnet.

  • The indicated pull force is theoretical and applies only to ideal conditions.
  • Do not use magnets in areas where people can suffer from serious injury in case of adhesion failure.

Metal splinters:

Neodymium (Rare Earth) and Ferrite (Ceramic) magnets are brittle. Colliding these magnets could cause them to crack or break.
Sharp splinters can launch away for several meters and injure your eyes.

  • Avoid collision of magnets.
  • Wear safety gear (glasses) when handling bigger magnets.
  • Make sure that people nearby also wear safety gear or keeps a safe distance.

Influence on people

According to studies done to this point, the magnetic fields of permanent magnets do not have a negative or positive impact on people. Although it is unlikely that permanent magnets can cause health risks, it cannot be ruled out entirely.

  • Try to avoid constant contact with magnets for your own safety.
  • Large magnets should be stored at least 1 meter away from your body.

Magnetic field:

Larger magnets produce a strong magnetic field that has a wide reach. They can damage electronic devices like laptops, televisions, compute hard drives, etc. They can also damage credit and ATM cards, data storage media, mechanical watches, hearing aids and speakers.

  • Please keep magnets away from objects and devices that could be affected by strong magnetic fields.
  • Keep a safe distance of at least 1 meter.


Some magnets are inflammable. When magnets are machined, the drilling dust could ignite.
Try to stay away from machining magnets and/or use appropriate tools with enough sufficient cooling water.

Heat Resistance

The maximum working temperature of Neodymium (Rare Earth) magnets is 80 to 200°C.
Most of the common grades like N38 lose most of their adhesion force if exposed to temperatures higher than 80°C.

  • Do not expose the magnets to heat that is higher than the recommended temperature for a specific grade.

Nickel Allergy:

Many of our magnets contain nickel, also those without nickel coating.

  • Some people can be allergic to nickel when they come into contact with it.
  • These allergies could develop from constant contact with nickel-plated objects.
  • Avoid constant skin contact with nickel-plated objects.
  • Avoid contact with magnets if you know that you have a nickel allergy.


Airplane navigation devices can be affected if magnets are not packed in the correct manner. Worst-case scenario, it can lead to an accident.

  • Certain regulations do apply when airfreighting magnets.
  • If the magnets are not packaged correctly, it can result in a higher cost or even forbidden to ship via Air Freight.


Improper packaging of magnets could cause disturbances in sorting machines and damage fragile goods in other packages because of the strong magnetic field.

  • Use lots of padding material in your box around the magnets.
  • When packaging magnets, you need to arrange them in a way that the magnetic fields neutralize each other.
  • In some cases where the magnetic field is very strong, sheet iron can be used to shield the magnets.

Splintering of Coating:

All of our Neodymium(Rare Earth) magnets have a nickel coating around them to protect them against erosion. This coating can crack or splinter on collision or large pressure. This can cause the magnets to be vulnerable to environmental influences like water and they could corrode.

  • Big magnets should be separated with cardboard.
  • Try to avoid collision of magnets and mechanical exposure like constant bashing or slamming of the magnets.

Machining of Magnets

Neodymium (Rare Earth) magnets are very brittle, heat-sensitive and they can corrode easily.

  • When trying to drill or saw these magnets with improper tools, can cause the magnets to break.
  • Extreme heat due to drilling or sawing can demagnetize the magnet.
  • The magnets will corrode once the coating is damaged.

Avoid machining or cutting magnets if you do not have the necessary knowledge. Let us rather try to find the bet solution for you.
