Metal detectors where you are sensing the location of the minerals by means of a thorough survey of a piece of land through them, and as they approach the area of the presence of minerals it makes a strong sound to alert the presence of a metal in that area.
The search for metals is started by rounding the device from an area and if the noise strength and the degree of jamming increase, this is proof of the presence of a metal in that area, and then the drilling and prospecting for this metal, taking into account that this device is simple to install and used to detect the minerals found in a For the outer layer of soil.

The metal detector is a modern device used to search for underground metals, or to achieve security and protection in many places, such as airports, borders between countries, or in some companies and others, but what some do not know is that it is possible to prepare this device at home, and that Using simple tools.
transmission coil: A collection of wires that may be present in an external or internal form, where electricity passes along the wire roll in one direction, but in the other direction a continuous magnetic field is generated every second, which moves to the ground to begin the process Metal detectors if any.
Reception coil: They are similar to transmissions, but they are internal, and their function is to capture the signals produced by the metals in the ground after the magnetic field is generated, amplified and alerted.
