Product Details

Rocks and ores in nature have different magnetic properties, which can produce different magnetic fields. It makes the earth's magnetic field change in local areas, resulting in geomagnetic anomalies. These anomalies can be studied by magnetic and magnetic instruments. Magnetic exploration is one of the common geophysical exploration methods. It is mainly used to find and explore related minerals (such as iron ore, lead-zinc ore, copper ore, etc.) and geological mapping.
