This is the reverse of the previous law. If you run electricity through a wire, it creates a magnetic field around it (this is how electromagnets work). But Maxwell added a crucial twist: even without a wire, a changing electric field (like in space) creates a magnetic field.
There are no "magnetic charges." If you snap a magnet in half, you just get two smaller magnets with their own North and South poles. You can’t have just one pole.
This proved they are linked. When these two forces dance together, they create a wave. We call that an electromagnetic wave. Depending on how fast that wave vibrates, it turns into different things we use every day: Radio waves (for your car stereo) Microwaves (for your popcorn) Visible light (the stuff you see) X-rays (at the doctor’s office) The "Invisible Field" Concept
If you are looking for a PDF summary of EM theory, 90% of it will focus on these four equations. They look terrifying in mathematical notation, but conceptually, they are surprisingly simple. Let’s translate them from "Physics" to "Human."
Changing magnetic fields create electric fields.
