Yes, magnets are generally allowed in hand carry luggage, but with a significant restriction based on their magnetic field strength.
Here's a breakdown:
The primary factor determining whether a magnet can be brought on a plane (in either carry-on or checked baggage) is its magnetic field strength. According to aviation regulations, any magnet or package containing a magnet that has a magnetic field exceeding 0.00525 gauss measured at 4.5 meters (approximately 15 feet) from any surface is prohibited from air transport.
Therefore:
- Magnets are allowed if their magnetic field is less than 0.00525 gauss at a distance of 4.5 meters. This likely includes small refrigerator magnets, magnetic toys, and similar items.
- Magnets are not allowed if their magnetic field exceeds this limit. This would likely include very powerful industrial magnets or large magnetic assemblies.
It's important to note:
- Enforcement: It is unlikely that TSA or airport security will measure the magnetic field of every magnet. However, if a magnet is suspected of exceeding the limit, it may be subject to further inspection and potential confiscation.
- Airline Policies: While the gauss measurement is the general rule, individual airlines may have their own specific policies regarding magnets. It is always a good idea to check with your airline before traveling.
- Hidden Dangers: Strong magnets can interfere with aircraft navigation systems and other sensitive equipment, which is why the magnetic field limit exists.
In summary, most small, common magnets are fine to bring in your carry-on. Large, powerful magnets might not be allowed, and ultimately the decision rests with airport security and potentially the individual airline.
