Pribciple description
The AMD-01 metal detector is used to detect metals by electromagnetic induction principle and can get high sensitivity for all metals including ferrous and non-ferrous metals. Ferrous metals will affect the distribution of magnetic force lines once they enter the detection area, and further affect the flux of fixed range. Non-ferrous metals will generate whirlpool effect once they enter the detection area, and will also chang the magnetic field distribution of the detection area.
In a word, the AMD-01 metal detector just uses electromagnetic induction principle and by detecting the electromagnetic field distribution to detect metals.
