Long term monitoring of the geoelectric field in the UK – 2012–2024 [PDF]
Geoscientific Instrumentation, Methods and Data SystemsDuring severe geomagnetic storms, rapid changes in the Earth's magnetic field can induce a significant geoelectric field in the conductive subsurface. This field can cause large potential differences in grounded systems that have long conductors between ...
