Ship’s permanent magnetic field

Distrurbance in Earth's Magnetic fields due to ship

The Earth’s magnetic field is the cause of the ship’s permanent magnetic field. The process of constructing a ship in the Earth’s magnetic field generates an appreciable amount of permanent-magnetism in the floating metal structure. Whenever there is a movement of the floating metal structure, the magnetic lines of force also move with it. This […]

Degaussing coils

Permanent magnetic field components of ship

The potency of a magnetic field is measured in terms of Gauss. And therefore, by definition, degausse means to reduce/eliminate the strength of the magnetic field. Degaussing coils are used to reduce the effect of Earth magnetic field on the ship’s magnetic field. A magnetic mine is activated when the earth’s magnetic field is distorted […]
