Electromagnetic Induction

Definition

Electromagnetic induction is the process of generating an electric current in a conductor by changing the magnetic field around it. It involves the interaction between electricity and magnetism.

Analogy

Imagine electromagnetic induction as charging your phone wirelessly using a wireless charger. When you place your phone on the charger, it creates a changing magnetic field that induces an electric current in your phone, allowing it to charge without any physical connection.
