Want to try your luck finding gold in an unclaimed land? All you need is a metal detector.
Metal detectors work on the principle of electromagnetism. Every metal (in solid state) has its own electric and magnetic field. Metal detectors have 2 circuits; one circuit, which is connected to a small battery which powers it up. This circuit is called as transmitter circuit. It sends electricity down the shaft to the coil at the bottom. The coil gets magnetized (changes its magnetic field) when this magnetized coil is swept on the ground and if there is a metal object near its sweep area, the magnetic field of the coil charges the metal object. The magnetic field of the metal detector changes the magnetic and hence the electric field of the metal object. This change in electromagnetism of the metal object is picked up by the receiver circuit of the metal detector. Due to the change in the magnetism of the coil of the metal detector, the electricity flows up the shaft of the detector to the receiver circuit. This change in the electromagnetism registered on receiver circuit confirms a metal detected by the coil.
Gold is not something that you can find in your backyard. And it is highly unlikely and improbable that you will stumble upon a pot of gold. Gold as metal can be found in the size of grain or even as big as nuggets. The place to find gold are the places where gold has been searched earlier and excavated from earlier. Placer deposits along the river streams and river beds can accumulate gold in small amounts.
You need to consider those states in the USA that used to produce gold in the earlier years. You cannot expect to find gold where it isn’t to be found so, research your search area. You can head out to the regional libraries or look for details on mines and geological surveys that shed light on details about the type of land and what metal it is abundant of. Also, you need to consider the federal laws of the area you are searching for and the stakes that it will have on the gold you excavate. If the land has a certain ownership and patent, there is a good probability that you might have ‘struck gold’.
