WebBecause of its distortion effects on the Earth’s magnetic field, the ship can act as a trigger device for magnetic sensitive ordnance or devices which are designed to detect these …
WebThe ships magnetic field is causing interference with the earth magnetic field and the compass need is subject to deviation and deflected away from the magnetic north pole. This time the ships compass needle is deflected to the west of the magnetic north pole. Deviation is caused by the interaction between the boats and the earths magnetic field. The term was first used by then-Commander Charles F. Goodeve, Royal Canadian Naval Volunteer Reserve, during World War II while trying to counter the German magnetic naval mines that were wreaking havoc on the British fleet. The mines detected the increase in the magnetic field when the steel in a ship concentrated the Earth's magnetic field over it. Admiralty scientists, including G…
