Abstract
One of the obvious applications of magnetometers is a system of magnetic vacuum which is able to minimize the influence of external magnetic fields on the operation of electronic instrumentation. In magnetic field systems, fluxgate magnetometers are commonly used in the capacity of absolute magnetic field sensors. However, the quality improvement of magnetic vacuum requires the improvement of the fluxgate performance, in particular, its sensitivity.
Highlights
Magnetic field measurement is the most important for and widely used in space and geophysical explorations [1,2], navigation, attitude and stabilizing control systems [3], quantum computer shielding systems [4,5], magnetic resonance imaging, brain imaging, flaw detection, non-destructive testing, etc

Summary
Magnetic field measurement is the most important for and widely used in space and geophysical explorations [1,2], navigation, attitude and stabilizing control systems [3], quantum computer shielding systems [4,5], magnetic resonance imaging, brain imaging, flaw detection, non-destructive testing, etc. One of the obvious applications of magnetometers are systems of magnetic vacuum which are able to minimize the influence of external magnetic fields on the operation of electronic instrumentation. Such systems utilize passive and active techniques of magnetic shielding. 2. Mathematical analysis In work [6] we suggested (1) for the output signal (electromotive force) and (2) for the fluxgate sensitivity. Mathematical analysis In work [6] we suggested (1) for the output signal (electromotive force) and (2) for the fluxgate sensitivity Both equations are for any harmonics irrespectively of the drive signal waveform and approximation method of the average magnetization curve.
