Abstract
Magnetotellurics is a frequency domain technique where the earth’s natural electromagnetic field is used as a source. The solar wind (charged particles emitted by the sun) interact with the earth’s magnetic field by ‘pushing’ it to and through, which induces currents in the earth’s crust according to Maxwell’s first law.
