    What is the principle of electromagnetic law?


    Rationale: This type of system includes a low frequency transmitter that can be strategically placed at a selected location to generate an electromagnetic signal that can completely cover most mines without the use of a transponder system.The system consists of two parts: a transmitter and a ground system for detection and communication.

    A compact loop antenna that is owned or placed in the strategic position of the mine by the miner is used to generate an electromagnetic field that can be sensed by the ground moving receiver.On the ground, a sensitive receiver detects the signal and locates the source.Once detected and positioned, a large ground transmitter is deployed above the trapped miners.
