Influence on people
According to the current level of knowledge, magnetic 
fields of permanent magnets do not have a measurable 
positive or negative influence on people. It is unlikely that 
permanent magnets constitute a health risk, but it cannot 
be ruled out entirely.
•  For your own safety, avoid constant contact with    
 magnets.
•  Store large magnets at least one metre away from
  your body.

Splintering of coating
Most of our neodymium magnets have a thin nickel-
copper-nickel coating to protect them from erosion.
This coating could splinter or crack due to collision or
large pressure. This makes them vulnerable to 
environmental influences like moisture and they could 
oxidise.
•  Separate big magnets, especially spheres, with a
  piece of cardboard.
•  Avoid collisions of magnets as well as repeated  

  mechanical exposure (e.g. blows, bashes).

Temperature stability
Magnets can withstand only a limited maximum 
temperature. Depending on the magnet material it ranges 
anywhere between 80 and 200 °C.
Most of our magnets lose part of their adhesive force 
permanently at a temperature of 80 °C.
•  Don’t use magnets in places where they are exposed to  
  extreme heat.
•  If you use an adhesive, don’t harden it with hot air.
