Magnets are very dangerous on any aircraft that fly in any international airspace today, as the magnetic compasses and their needles are very fine, delicate instruments that require the most utmost precision. In certain cases, there are multiple calibration instruments that stabilize the magnetic readings in order for the pilots to accurately determine certain information. This is necessary, because the electrical current flowing through the wires throughout the airplane creates a small magnetic field, but influences the readings on the magnetic compass. As a result, the airplane mechanics and controllers initially calibrate the readings outside of the airplane when there is no external influence of magnetic forces.
Hope this helped, thanks!
