Deperming has critical importance and can't be ignored. This process is different from the types of Degaussing as it nullifies permanent magnetic field

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...

The magnetic field induced in the floating structure is dependent on the potency of the Earth’s magnetic field and the layout and direction of floating structure w.r.t. the Earth’s magnetic field. As discussed earlier, The ship’s induced magnetism is also a cause of the...

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,...
