The Effect of the Depth of the Non-Conducting Layer on the Induced Magnetic Field at the Peruvian Dip Equator

The internal part of the geomagnetic daily variations at the Peruvian dip equator shows the presence of an anomaly in the earth conductivity. This anomaly is further investigated in the present work using the external and internal parts of those variations, found in a previous work. The field induce...
