Abstract

The method for active suppression of electromagnetic field of industrial frequency (EMF) was developed for two cases: large spaces, in which the EMF is created by single known source (like a power line, transformer or any other electric apparatus) and confined spaces in which EMF is created by several sources (around computers, houses, offices). The method is based on decomposing the total EMF vector into the three components and further suppression of each component. This is accomplished by means of creating anti-EMF using the system of windings of different forms. An automatic control system with negative feedback is used for this goal.
