the article says:
A new type of magnetic field detection system, which can operate at a frequency below 1 kHz, is proposed and developed. The system consists of a 40-turn-coil to generate the magnetic field and a magneto resistive sensor to detect both the amplitude and the phase signal of the magnetic field induced by eddy-current and magnetization of the samples. The magnetic field detection of ferro- and non-magnetic samples using the system is demonstrated and discussed.
accidentaly , last days I made a receiver 100Hz-11Khz
if you find a operator uder 1Khz , maybe I say maybe ....or if someone can give us a design????
να τα παντρέψουμε , τι λές Γιώργο ?
friendly , epitopios
