Whether or not you can take a magnet through airport security depends on the strength of the magnet. If the magnetic field is more than 0.00525 gauss (or 5.25 milligauss) measured at 4.5 m (15 feet) from any surface of the package or magnet, it cannot fly. This is because strong magnets can interfere with the aircraft's navigation and electronic equipment. However, magnets of this strength are typically not available to consumers, so you should be fine bringing small magnets or magnetic toys in your carry-on or checked luggage.

Strong magnets are banned from planes as they can interfere with navigation
Strong magnets are banned from being brought onto planes due to their potential to interfere with the aircraft's navigation and electronic equipment. This interference is caused by the magnitude of the magnetic field of such objects. The Federal Aviation Administration (FAA) has set a limit of 0.00525 gauss or 5.25 milligauss at a distance of 15 feet from the magnet as the threshold above which magnets are not permitted on aircraft. This restriction applies to both carry-on and checked luggage.
Magnets that exceed this threshold can disrupt the plane's compass and other navigation systems, posing a serious security risk. Therefore, it is crucial to adhere to the guidelines and refrain from bringing strong magnets on board. However, it's important to distinguish between normal consumer magnets and strong industrial or earth magnets. Typical consumer magnets found in magnetic toys, games, fridge magnets, and souvenir magnets are generally safe and allowed on planes. Their magnetic strength is significantly lower than the restricted level and does not pose a risk to the aircraft's systems.
In the United States, certain procedures can be followed to transport strong magnets safely. The Transportation Security Administration (TSA) provides guidelines and arrangements for transporting such magnets. While specific processes may vary, driving or shipping magnets by ground shipping within the country is generally a safer option than air travel.
It is worth noting that some individuals have reported varying experiences with transporting magnets on planes. Some have suggested that certain aircraft, such as the 737, 747, or Airbus, may accommodate magnets in checked luggage if they are properly packaged and padded. However, these reports are based on personal experiences and may not reflect universal policies or guidelines.
To ensure compliance and avoid any issues, it is always advisable to refer to the official guidelines provided by aviation authorities and consult with relevant organizations, such as the TSA, for specific instructions and arrangements regarding the transportation of strong magnets.

Magnets with a field strength of >5.25 milligauss at 15 feet are prohibited
While there is no explicit information on taking magnets through airport security, there are strict rules about shipping magnets by air. According to the Federal Aviation Administration, magnets with a field strength of >5.25 milligauss (0.00525 gauss) at 15 feet (4.5m) are prohibited from being transported by aircraft. This is because magnets with a field strength above this limit can interfere with navigational equipment.
To put this into context, a group of small magnets, such as those measuring 1/2" or less, will likely fall far below this limit. Even a stack of multiple magnets will often have a weaker field than a single magnet. However, the arrangement of magnets can impact the overall field strength. For example, placing magnets side by side with their north poles facing opposite directions will result in a weaker magnetic field than a single magnet.
To measure the field strength of a magnet, you can use a milligauss meter or a simple compass. If you use a compass, place it 7 feet away from the magnet along an east-west line and observe how much the needle deflects. If the deflection is about 15 degrees, the magnet's field strength is likely above the 5.25 milligauss limit.
It is important to note that the inexpensive sensors in most phones are not sensitive enough to measure changes in magnetic fields at this level. Therefore, if you need to measure the field strength of your magnets accurately, you may need to invest in a calibrated meter, which can cost hundreds of dollars.

Industrial magnets are not allowed in carry-on or checked luggage
It is important to understand the risks associated with carrying industrial magnets through airport security. While you may be able to pass through security with small, consumer magnets, such as magnetic toys, games, fridge magnets, and souvenir magnets, the same does not apply to industrial magnets. Industrial magnets are not permitted in carry-on or checked luggage due to their strong magnetic fields, which can interfere with aircraft navigation and electronic equipment.
The interference caused by industrial magnets can have serious implications for flight safety. Their powerful magnetic fields can affect the plane's compass and other sensitive instruments, potentially leading to inaccurate readings and navigational errors. This poses a significant risk to the aircraft and the safety of its passengers and crew. Therefore, it is crucial to adhere to the regulations regarding the transportation of such items.
The regulations regarding industrial magnets apply to both carry-on and checked luggage. Even if an industrial magnet is enclosed within a bag or suitcase, the magnetic field it generates can still impact the aircraft's systems. As such, it is essential to follow the guidelines and refrain from attempting to bring industrial magnets on board an aircraft.
Additionally, it is worth noting that the decision to allow or prohibit any item through airport security ultimately rests with the TSA officer on duty. Even if an item is generally permitted, it may be subject to additional screening or prohibited if it triggers an alarm, appears tampered with, or raises other security concerns. Therefore, it is always advisable to check with the relevant authorities or consult official sources for the most up-to-date information regarding the transportation of industrial magnets.
If you need to transport industrial magnets, alternative methods such as ground shipping or transporting them in a private vehicle are recommended. These methods ensure the magnets are not in close proximity to an aircraft, mitigating the risks associated with their strong magnetic fields. By opting for these alternatives, you can safely transport industrial magnets while complying with the relevant safety regulations.
