Before you download any PDF, you need the skeleton of the theory. Here is electromagnetism in three bites.
When charges move, you get an electric current. Think of a copper wire as a water pipe and electrons as tiny water droplets. Voltage is the pressure pushing them; current is the amount flowing; resistance is the pipe width.
Michael Faraday discovered that if you move a magnet through a coil of wire, electricity flows. Yes, it is that simple. The voltage generated depends on how fast you move the magnet. Electromagnetism For Dummies Pdf
These are four complex equations that describe everything about electromagnetism. You don’t need to solve them, just know that they proved:
For centuries, people thought electricity and magnetism were two different things. A guy named James Clerk Maxwell came along in the 19th century and proved they are actually two sides of the same coin. Before you download any PDF, you need the
Everything is made of atoms. Atoms have protons (positive charge) and electrons (negative charge).
The Pocket Guide to Forces, Fields, and Physics For centuries, people thought electricity and magnetism were
Physics can get math-heavy, but here are the three laws you need to know to sound smart at a party.
