Can the magnet be transported by air? The answer is yes. The premise requires special degaussing, the so-called degaussing, in fact, the magnetic does not disappear, but the re-combination of the items in the unit package, so that the magnetic display of the unit packaging to the outside meets the national aviation safety requirements.
To prevent interference with aircraft instruments, especially compass instruments, shippers should package magnetic materials in the following manner:
1. The opposite magnetic poles of instruments and devices such as magnetrons and illuminometers must be placed opposite each other.
2. The permanent magnet material must be equipped with a magnetically-loaded armature or a screen clamp to prevent the magnetic field from causing deviation of the compass meter. Passive decoding degaussing plates are commonly referred to as foam packaging.
3. Each package of magnetic material must be properly marked and labeled in accordance with the rules of the International Air Transport Association.
4. Ensure that the magnetic field strength measured at 4.6 m (15 ft) from the surface of the package does not exceed 0.418 A/m (0.00525 gauss) before shipment.
5. It is recommended to pack wooden boxes outside the large pieces.
