We investigate one of the most sensitive devices for measuring magnetic fields, the, so-called, AMOR magnetometer. The device exploits a specific nonlinear optical phenomenon (amplitude-modulated nonlinear magneto-optical rotation) for ultra-precise magnetic field detection. It allows measuring the field with a sensitivity of 10^-14 T/Hz^-1/2 within a dynamic range of 10-4 T. Such high sensitivity and the dynamic range covering the Earth magnetic field are desired in context of many practical application of the device. By elaborating the electronic model of the magnetometer we study its different characteristics in various arrangements. It allows us to optimize the device regarding different requirements, e.g., technical simplicity, data processing, etc. It is shown that the device may be automated operating it in the self-oscillation mode. Particularly, we show that the magnetometer instantly responses to the magnetic field change. Our numerical analyses are confirmed with experimental results obtained in one of the arrangements.
