Abstract: Induction magnetometers (IM) are probably the most widespread devices used for magnetic field variations measurements. They may cover the frequency band from ~10-4 till 106 Hz and have dynamic range up to 120 dB. The development of wide-band and especially high frequency IM with magnetic flux feed-back meets serious problems with the providing of their stability. The present paper is devoted to the analysis and discussion of the method of ensuring of IM stability. The theoretical analysis and the results of experimental verification confirm the efficiency of the proposed method which uses the properly selected correction circuits.
