Electric field

Electromagnetism is the branch of physics that studies the interactions between electric charges and the resulting electric and magnetic fields, unifying electricity, magnetism, and light into a single framework.

It explains how moving charges create magnetic fields and how changing magnetic fields generate electric fields, forming the basis for technologies like transformers and electromagnets.

As we are using high-tech equipment here.

We have a nice Core i7 laptop that's quiet, hooked to a mixer and a microphone, and I am able to do this show looking at a decent sized digital screen.

These fields are fundamental in nature and can exist in space.

far from the charge or current that generated them.

Remarkably, electric fields can produce magnetic fields and vice versa, independent of any external charge.

A changing magnetic field produces an electric field, as the English physicist Michael Faraday discovered in work that forms the basis of electric power generation.
