Magnetic Shielding: Transporting Magnets By Air

Shipping Magnets By Air

In order to comply with IATA regulations regarding magnetic leakage, magnetic materials, including permanent magnets, must adhere to strict guidelines when being transported by aircraft. These regulations are outlined in the IATA Dangerous Goods Regulations, which apply to all dangerous materials transported by air, including magnets. At Tengye, we conduct magnetic leakage tests for all our magnetic products that are intended for air transportation, ensuring full compliance with these regulations. Rest assured, we can provide certificates verifying the results of these tests when necessary.

Magnetic Shielding

Magnetic shielding doesn’t require complex technology; it’s a simple yet effective method to control magnetic fields. By utilizing magnetic materials like iron plates, we can easily intercept and absorb the magnetic field lines emitted by permanent magnets. These field lines are naturally drawn to and attach themselves to the iron plates, significantly reducing magnetic field leakage.

To optimize the shielding process, thicker iron plates with higher iron content prove most efficient. When dealing with larger and stronger magnets, multiple iron plates can be strategically arranged or placed at a distance to ensure effective control of magnetic field lines.

Visualize the effectiveness of magnetic shielding with our simulation: enclosing a sizable φ100mmX70mm neodymium magnet with iron plates. As demonstrated in the diagram, the iron plates successfully confine the magnetic field lines, preventing any leakage beyond the shield’s boundaries.
