ABOUT MAGNETS   >   Safety policies

Toxicity of magnets

With regard to chemical composition, magnets comply with the European directive (2002/95/EC).
RoHS (Restriction of Hazardous Substances).
Ferrite magnets are not toxic. In an extreme environment (acids) a small amount of barium may be released. In many cases barium is replaced by strontium.

The toxicity of magnets from rare earths is low and during external contact of the magnet there is no danger of intoxication thanks to the atoms being firmly bonded in the material structure.

The effect of magnetism on human beings

So far no detrimental effect of the magnetic field on human beings has been confirmed, as opposed to, for example, x-ray radiation. In medicine, the magnetic field is used in diagnostics (NMR - nuclear magnetic resonance). Some methods also take advantage of the effect of the magnetic field from permanent magnets or electromagnets in physiotherapy. Currently, it is more used in alternative medicine.

Persons with a cardio stimulator or other sensitive electronic medical devices are prohibited from handling magnets and approaching magnets to a distance of less than 0.5 m.

Handling magnets

Manipulate carefully when two magnets or a magnet and a steel object are approaching.
Given the strong forceful effect the magnet might be damaged or an injury might occur! Do not leave magnets lying about.
When working with powerful and large magnets wearing gloves is recommended.

It is prohibited to handle magnets in an environment with an explosion hazard due to the possibility of a spark striking.

Magnets are particularly brittle. As a result, tiny pieces may break off during handling. It is necessary to protect the eyes with goggles.

During grinding fine dust is created. Its inhalation might cause respiratory problems, or possibly start another illness. It is necessary to use protective equipment (respirator).

Do not place magnets near:
  • sensitive electronic and mechanical devices
  • persons with a heart stimulator
  • magnetic recording media (credit cards, floppy disks, tape recorder and video cassettes, etc.)

Magnet damage risks

Risk of demagnetising a magnet:
  • during contact with a stronger type of a magnet (e.g. Anico in contact with NdFeB)
  • in a very strong magnetic field
  • when exceeding the maximum working temperature
Risk of magnet destruction:
  • in aggressive chemicals (depending on the type)
  • in a hydrogen atmosphere
  • by physical impact
  • by radiation
The individual types of magnet differ in resistance to the above effects. Contact us for more detailed information.
