Can I use magnets outdoors as well?

Water-proof neodymium magnets

Two kinds of neodymium magnets are predestined for outdoor use:
  • Coated magnets (pictured is a rubberised magnet) are completely coated by a plastic layer.
  • Sew-in magnets are shrink-wrapped in a PVC cover.
That makes both types perfectly suitable for longterm use outdoors, in wet surroundings (e.g. bathroom) or even under water (e.g. in aquariums). At the same time, they are much stronger than ferrite magnets of the same size.

Other neodymium magnets

We recommend using neodymium magnets exclusively in dry indoor areas.
Untreated neodymium magnets oxidise very quickly and break. To protect our magnets from corrosion, they have a thin nickel copper nickel coating.
The coating offers a certain protection against corrosion, but is not resistant enough to withstand long-term outdoor use.

Therefore, please use neodymium magnets only in dry indoor areas or protect the magnets from environmental influences with anti-corrosion paint, transparent varnish or waterproof packaging.
Avoid damaging the protective coating and check magnets frequently for rust. Please keep in mind that you will need to replace rusting magnets.

Ferrite magnets

Ferrite magnets are insensitive to humidity and can be used outdoors without rusting. A special protection is not necessary.
Pot magnets with ferrite magnets are also suitable for outdoor use. Surface rust may develop on the pots over time, but that does not impact the performance of the magnets. The magnets themselves are rust-proof.
Ferrite magnets are also resistant to most chemicals. However, solvents and certain concentrated acids may harm the magnets.

Magnetic tape and magnetic sheet

Since they don't rust, magnetic tapes and sheets can also be used outdoors. However, UV radiation may make the material brittle. Therefore, you have to take into account that you may have to replace the material from time to time.
When it comes to magnetic tapes and sheets, you need to consider the FAQ about self-adhesive products.
