Electromagnetic Field

Definition

An electromagnetic field is a physical field produced by moving electric charges or changing magnetic fields. It consists of both an electric field and a magnetic field that are perpendicular to each other and propagate through space.

Analogy

Think of an electromagnetic field as a dynamic duo performing on stage. The electric field is like the singer, creating vibrations in the air, while the magnetic field is like the guitarist, strumming strings that generate invisible waves. Together, they create a harmonious performance that travels through space.
