Basic principles for determining the components of the Earth’s magnetic field on moving ferromagnetic objects (fundamentals of field separation theory)


St. Petersburg Branch of the Institute of Terrestrial Magnetism, Ionosphere and Radio Wave Propagation, Russian Academy of Sciences, Muchnoi per. 2, St. Petersburg, 191023, Russian Federation

A method for determining the Earth’s magnetic field components on a moving object having its own magnetic field is presented. A simplified scheme is considered to illustrate the method of problem solution. Equations yielding a correct solution for both the simplified scheme and a real moving ferromagnetic object are derived. Technological problems are listed that can be solved by measuring the Earth’s and other magnetic fields onboard a moving object with an arbitrary magnetic field of its own.
