Separation of local and regional information in geomagnetic response functions using hypothetical event analysis
Magnetic fields of galvanic or inductive origin can be distinguished by their phase behaviour. Pure distortion fields are in-phase with the regional electric field. Hence the magnetic phase of the galvanic response approaches the regional impedance phase, as distortion effects outweigh the inductive...
