What is Electricity & Magnetism?
Electricity and magnetism are two manifestations of the same fundamental force. This area of physics powers modern civilization—from light bulbs to smartphones to power grids. Understanding circuits and magnetic fields helps you grasp how electrical systems work and how electricity and magnetism relate to each other.
In this area, you'll explore electric current and voltage, circuit components, and magnetic fields. These topics show how electricity works in practical applications and how it connects to magnetism through deeper physical principles.
