N2 - To measure the moisture content of soil, we developed a method that measures the magnetic field generated when the primary magnetic field Is exposed. Soil contains two different types of materials: water as a diamagnetic material and Iron sand as a ferromagnetic material. Water shows a constant phase shift from the primary magnetic field as well as a frequency dependence of the magnetic field strength, and iron sand showed the opposite characteristics. Using these magnetic properties, a moisture content signal was extracted, even with Interference of the iron sand.
