The behavior of magnetic field intensity will be
performed at different depths and locations. In our research, the behavior of magnetic field decreases to zero when the depth of soil increases. As well as the case of increasing the space between source - receiver, the magnetic field decreases to zero too. The values of a and b are important role for the conduction of the ground and effect to the magnetic field quantities as well. For the high conductive ground (a and b > 0), the response of magnetic field will be very strong. In the opposite direction (a and b < 0), the response field will be very weak.
