A Helmholtz coil is a device for producing a region of nearly uniform magnetic field, named after the German physicist Hermann von Helmholtz. It consists of two electromagnets on the same axis, carrying an equal electric current in the same direction. Besides creating magnetic fields, Helmholtz coils are also used in scientific apparatus to ...
USS. Nautilus. (SSN-571) USS Nautilus (SSN-571) was the world's first operational nuclear-powered submarine and on 3 August 1958 became the first submarine to complete a submerged transit of the North Pole. Her initial commanding officer was Eugene "Dennis" Wilkinson, a widely respected naval officer who set the stage for many of the protocols ...
Plate number coil. A plate number coil (PNC) is a United States postage stamp with the number of the printing plate or plates printed on it.

Air-independent propulsion. Air-independent propulsion ( AIP ), or air-independent power, is any marine propulsion technology that allows a non-nuclear submarine to operate without access to atmospheric oxygen (by surfacing or using a snorkel ). AIP can augment or replace the diesel-electric propulsion system of non-nuclear vessels.
