Electromagnetism is the study of how electric charges and magnetic fields interact. For a beginner, the field can be broken down into four foundational pillars [5, 25]: Electric Charges & Fields

When electrons stop sitting still and start marching in a line through a copper wire, that is (Amps). This is your wall outlet. Without flow, you have a battery. With flow, you have light bulbs.

Magnetism is not a separate force but rather the result of electric charges. Electromagnetic Theory And Electrodynamics By Satya Prakash

Electromagnetism is a branch of physics that deals with the study of the electromagnetic force, a type of physical interaction that occurs between electrically charged particles. This force is responsible for holding atoms and molecules together, and it's also what allows us to use electricity in our daily lives.

This book is generally praised for making complex, "microscopic" physics concepts intuitive through physical analogies and everyday examples.
