Destination Gold Detectors Vocabulary page will be growing and welcomes you for definitions related to gold and metal detection.
Eddy currents (also called Foucault currents) are loops of electrical current induced within conductors by a changing magnetic field in the conductor according to Faraday's law of induction. Eddy currents flow in closed loops within conductors, in planes perpendicular to the magnetic field.
Gold Ore is rather than Gold specimens, gold joint with another mineral. The ore usually contains very small traces of gold. To extract the gold, the ore is crushed and then the gold is separated by the ore by an additional process.
