Electromagnetic Induction

Electromagnetic induction is the process by which a changing magnetic field generates an electric current in a conductor. For instance, moving a magnet near a coil of wire creates electricity, which is the principle behind generators. This phenomenon is foundational in electromagnetism, linking electricity and magnetism, and is crucial for many technologies, including power generation and transformers. Electromagnetic waves, such as light, also arise from changing electric and magnetic fields, illuminating how these forces interplay in different forms. Thus, electromagnetic induction illustrates the dynamic relationship between electric and magnetic fields in our world.
