What does electromagnetic prospecting utilize?

Electromagnetic prospecting primarily utilizes mine detectors and soil-conductivity meters. This method is based on the principles of electromagnetism, allowing researchers and archaeologists to detect buried materials by measuring the ground's electrical conductivity.

Mine detectors are designed specifically to find metallic objects beneath the surface, making them invaluable for locating artifacts, buried structures, or even mining resources. Soil-conductivity meters complement this by assessing the conductivity of the soil itself, which varies based on its composition and the presence of buried materials. Together, these tools provide a non-invasive means of surveying an area, helping to identify potential sites of interest without disturbing the ground.

This technique stands apart from methods that focus on different physical principles or tools, such as infrared technology, X-ray imaging, or standard excavating tools, which serve other purposes or rely on direct excavation and observation.
