Abstract

The residual magnetization of parts may cause negative effects: in aircraft, it yields a substantial compass error and the unexpected actuation of automatic elements, while during electrical welding on major pipelines, it does not allow one to obtain a high-quality weld. The designs, techniques, and devices intended for demagnetization of large objects, which are difficult to demagnetize using conventional means, are proposed.
