In the 1860s, a Scottish scientist named James Clerk Maxwell wrote down four math equations that explained literally everything about electricity and magnetism. While the math requires advanced calculus, the meaning behind them is incredibly straightforward. Here is Maxwell's theory translated into plain English: Law 1: Gauss’s Law (Charges Make Fields)

At its absolute core, electromagnetic theory explains how talk to each other.
In the 1800s, scientists realized they are two sides of the same coin. If you move an electric charge, you get a magnetic field. If you wiggle a magnet, you get an electric current. This is why we call it 2. The Four Rules (Maxwell’s Equations) This guide is designed to flip that script

Everything from and WiFi to X-rays and Visible Light is an electromagnetic wave. The only difference is how fast you "shake the rope" (the frequency). 4. Why Does This Matter to You? Your Smartphone: Uses EM waves to talk to cell towers.
