The entire framework of classical electromagnetism is neatly summarized by four mathematical equations known as . Compiled by James Clerk Maxwell, they describe how electric and magnetic fields are generated and altered by each other and by charges. Conceptual Meaning Gauss's Law for Electricity
How magnets create fields and the force they exert on moving charges (Lorentz force). 4. Electromagnetic Induction

Before the 19th century, electricity and magnetism were thought to be unrelated phenomena. That changed in 1820 when Danish physicist Hans Christian Ørsted discovered that an electric current flowing through a wire deflected a nearby magnetic compass needle.

Leo looked at his nail. He had wrapped the wire around it maybe ten times, loose and messy. He sighed, grabbed a fresh spool of insulated copper, and started over. This time, he didn't just wrap it; he disciplined it. He wound the wire tight, layer after layer, until the iron nail was buried in a thick, gleaming orange cylinder of copper.
If you download a textbook, you’ll see four famous equations by James Clerk Maxwell. Don't let the math scare you; they essentially say four simple things: Electric charges create electric fields.

This describes induction. It says that the faster you move a magnet through a coil of wire, the more voltage you create.
That afternoon, Grandpa Marco sat on the bench outside and watched children chase paperclips with magnets, eyes bright even behind the slow lens of years. Lina walked over with the Copper Compass tucked under her arm. He nodded, the lines at his temples deepening. “Did you get the book?” he asked. : All objects, including human bodies , emit
—who was sitting nearby in the form of a compass—suddenly twitched. Every time This was the first lesson of their story: Moving electricity creates magnetism. realized that when
was in a hurry, he wrapped the space around the wire in an invisible hug called a Magnetic Field . The faster ran, the tighter and stronger that hug became. The Push and the Pull Not to be outdone,
Historically, scientists treated electricity and magnetism as two completely separate phenomena. Today, we know they are two sides of the exact same coin. The presence and flow of electric charge.
