Whose equations describe electromagnetism?
Quick Answer
Scottish physicist James Clerk Maxwell unified electricity, magnetism, and light into four elegant equations in the 1860s โ a foundation of modern physics.
The Full Story
In the 1860s, James Clerk Maxwell showed that electricity and magnetism are two aspects of a single force, capturing their behavior in a set of equations now known as Maxwell equations. Remarkably, the equations predicted waves traveling at the speed of light, revealing that light itself is an electromagnetic wave. This insight opened the door to radio, television, radar, and all wireless communication. Albert Einstein kept a photograph of Maxwell on his study wall and credited him as a key influence on relativity. Many physicists rank Maxwell alongside Newton and Einstein.
