There are different factors that cause the magnetic field emitted by any type of magnetic detector such as pulse metal detector or TR metal detector or VLF metal detector or any type of magnetic detector or magnetic detector or function generator or magnetic wave system to not penetrate deep into the earth and a The general factor of the curved state is the combination of the high negative electric charge in the magnetic field emitted by the magnetic detector or magnetic metal detector with the negative electric charge belonging to the earth’s magnetism which causes disturbances during movement with the searcher or loop or magnetic sensor
