Ship deperming

WebTo establish such a deperming protocol, we conducted a theoretical study using Preisach modeling for the Flash-D protocol. Magnetic coercivity distributions were derived from B–H curves representing the material properties of the warship, and a deperming protocol that is effective on particles was proposed. WebMay 19, 2013 · During the deperming procedure large coils are wrapped around a ship and DC currents are used to cancel the remaining permanent magnetism of the ship. The process is repeated a number of times slowly whittling down the permanent magnetic field of the ship, making it “magnetically invisible”.
