METHOD FOR REPRODUCTION OF ALTERNATING MAGNETIC FIELD

摘要

Method for reproduction of alternating magnetic field based on adding magnetic fields obtained as result of current flow by resonance contours formed by means of active resistances, capacitors and inductances adjusted to given harmonic of current, at that in each contour one measures phase shift of current of contour with respect to first harmonic and adjusts phase of each harmonic to reproduced field with comparison of value of signal of current set for formation of alternating magnetic field with separation of difference signal and by its value one adjusts value of set current.
