Аnnotation: In the article presented experimental results of side-by-side test of component magnetic sensors various types – coil sensor, torque optical-mechanical sensor, and magnetomodulation sensor. The experimental estimation of self-noise being tested sensors are brought and compared with early known data. It has been experimentally de-termined, that most reliable a stable estimation of self-noise may be obtained in the group of same type sensors or with using knowingly less noisy sensor as reference. It is shown that experimental estimation of self-noise for coil sensor may significant differs from theoretical one in low frequencies range. It is shown that coil sensor has best noise performance, whereas sensor based on magnetomodulation transducer was the noisiest.
