Using Eliashberg theory, the required electric field strength is quantified as approximately 10 8 V/m, matching experimental observations and enabling advances in superconducting electronics.

The field is weak, only 0.55 volts — about as strong as a watch battery, Collinson says. But that’s strong enough to control the shape and evolution of the upper atmosphere, features that ...

The Earth's ambipolar electric field is a phenomenon that occurs in the ionosphere, the upper part of the Earth's atmosphere, where ions and electrons are present in significant quantities.

Dreams of a unified field theory Einstein's aim was to explain electromagnetism as a geometric property of four-dimensional spacetime. He continued this work until his death in 1955.
