The link between general relativity and electromagnetism becomes clear by assuming that the so-called four-potential of electromagnetism directly determines the metrical properties of the spacetime.

While Maxwell’s electromagnetism is an incredibly powerful theory, it is a classical model just like Newton’s gravity and general relativity.

Electromagnetism and how it pushes and pulls objects is responsible for the energy in things like batteries and magnets, but it also includes light, which is just waves of electromagnetic radiation.

In 2018, as he prepared to be awarded the Fields Medal, math’s highest honor, Akshay Venkatesh carried a piece of paper in his pocket. On it, he had written a table of mathematical expressions that ...

But as a co-discoverer of electromagnetism he had an intimate practical feel for the subject, and he believed there must be some sort of electromagnetic “field” filling up the space ...

Einstein's aim was to explain electromagnetism as a geometric property of four-dimensional spacetime. He continued this work until his death in 1955. The work was not completed.

GCSE WJEC Electromagnetism – WJEC Calculating voltage If electric current flows in a coil, it experiences a force and moves. Spinning a magnet in a coil of wire generates electricity.
