Design and Release of Reparative Characteristic Online Simulator of Ferromagnetic Ships Using Electrical Current Loops

One way of detecting ships or submarines is the observation of magnetic field signature around the object. Ships or submarines can be assumed as a collection of closed circuit of electrical currents. The electrical current of each close circuit must be properly regulated. The main purpose is production of a magnetic field equal to the magnetic field around the ship but with the opposite direction. By using this method, the magnetic field can be effectively reduced. This simulator is designed in C# language and it was named General Magnetic Compensation. The inputs of this software are geometry, location and magnetic field and the output is electrical currents of each closed loop, thus making the magnetic field reduced around the submarine. Accuracy and validity of the new software was investigated by analytical relation of magnetic field for proper geometry. Then a submarine was simulated in COMSOL and data of this simulation were used in General Magnetic Compensation software. The results were in great agreement with the results of the COMSOL software and could predict the magnetic field well.
