Review of geomagnetically induced currents

open access: yes地球与行星物理论评, 2022
Geomagnetic disturbances caused by solar activities induce geoelectric fields on the earth's surface, which generate geomagnetically induced currents (GICs) in electrically conducting systems.

Geomagnetic Pulsations Driving Geomagnetically Induced Currents

open access: yesSpace Weather, 2021
Geomagnetically induced currents (GICs) are driven by the geoelectric field induced by fluctuations of Earth's magnetic field. Drivers of intense GICs are often associated with large impulsive events such as coronal mass ejections.
