FAQ - Frequently Asked Questions
Can I send magnets by mail?
- Arrange magnets antiparallel
- Increase the distance between magnets and package
- Shield magnets with iron sheets
Arrangement of magnetsIf you send several magnets together you can massively reduce the magnetic field through the proper arrangement of magnets within the package. Two or more magnets should be arranged in a way that half of the magnets are parallel to the other half, the poles pointing in opposite directions.
Shielding with sheet steel
Paper clip testIn order to check if a package is not overly magnetic, its surfaces would have to be measured with a teslameter and an acceptable critical value would have to be determined. This is often not possible. An every-day-life test is the paper clip test:
You put a paper clip to all sides of the package and it should not stick, but fall down. If you want to be even stricter, you can hold the surface not upright but at an angle of e.g. 45 degrees and see if the paper clip slides over the entire surface. If this test is successful, you should not have any problems during transport and the package should arrive safely without getting caught or damaging other items.
Shipping of different magnet typesDuring transport, these minimum distances between the different magnet types need to be observed to prevent damages and mutual demagnetisation:
|Ferrite||-||22 mm||0 mm|
|Neodymium||22 mm||-||43 mm|
|AlNiCo||0 mm||43 mm||-|
