Can magnets be transported by air? The answer is yes. The so-called demagnetization, in fact, the magnetism does not disappear, but the items in the unit package are recombined to make the magnetism displayed on the outside of the unit package meet the national requirements for air safety transportation.
In order to prevent interference to aircraft instruments, especially compass instruments, the shipper shall pack the magnetic materials in the following ways:
1. The opposite poles of magnetron, illuminometer and other instruments and devices shall be placed relative to each other.
2. Permanent magnet material must be equipped with magnetic keeper or screen to prevent compass instrument deviation caused by magnetic field. Passive decoding of the degaussing board is commonly referred to as foam packaging.
3. Each package of magnetic materials must be correctly marked and labeled in accordance with the rules of IATA.
4. Ensure that the magnetic field strength measured at 4.6m (15ft) from the package surface does not exceed 0.418a/m (0.00525 Gauss) before shipment.
5. Wooden case packing is recommended for large pieces.
