Magnetotellurics
Magnetotellurics (MT) is a passive geophysical method that uses natural variations in Earth's magnetic and electric fields to characterize subsurface electrical conductivity. Developed by Louis Cagniard in 1953, MT measures the impedance relationship between naturally occurring magnetic fluctuations (from solar wind and ionospheric currents) and the resulting electric field, providing information about crustal and upper mantle structures.
