What are the four degaussing coils found in a typical system?

In a typical degaussing system, the four coils are specifically designed to minimize magnetic signatures of a vessel, thereby enhancing stealth capabilities. The terms associated with these coils represent their locations and functions in the system.

The correct sequence of the coils is known as FP-QP, M, A, FI-QI. Each coil performs a unique function within the overall degaussing system:

• The FP (Fore Perpendicular) and QP (Quarter Perpendicular) coils work together to counteract the magnetic signature generated at the bow and sides of the vessel.

• The M (Midship) coil is positioned along the centerline to address magnetic interference from midship portions.

• The A (Aft) coil compensates for magnetism emanating from the stern.

• Finally, the FI-QI (Ferrous Interceptor-Quarter Interceptor) coils are used to fine-tune the cancellation of magnetic fields.

This configuration is essential for effective degaussing. The arrangement reflects operational requirements by addressing magnetic influences from different sections of the vessel, thereby ensuring a comprehensive reduction of magnetic signatures. Understanding this layout is crucial for technicians working with gas turbine systems and marine technologies.
