De-Magnetising a Ships take away - Essay ExampleThe soft iron parts get temporarily magnetized due to the see of horizontal and vertical components of earths magnetic field which flows through the huge ship when kept on the think about for a long time. 1 So the entire ship behaves like a magnetic after edifice for which it is subjected to two types of dangers. Firstly, the magnetic compass will not work correctly in gradient the ship and second the ship will be affected by magnetic mines inside the water. So we have to shoot ships magnetism and the process is called degaussing. Above all we have to place magnets and magnetic materials on each side of the compass inside the ship to keep its direction exactly towards the magnetic meridian.It is a process to bow out ships magnetism. 3 This is done by winding few turns of insulated wire around the ship and passing a well-grounded current so as to create an opposite magnetic field to that of the ships magnetic field. This will con sume ships magnetism by the demagnetization process. A steel hulled ship is like a huge planless magnet with large magnetic field surrounding it as the ship moves through the water, this field in like manner moves. The ship can act as a trigger device for magnetic sensitive weapon or devices, which are designed to detect these distortions.
