Electromagnetic Induction
Electromagnetic induction is a fundamental principle in physics and electrical engineering where a changing magnetic field induces an electromotive force (EMF) or voltage in a conductor. This phenomenon, discovered by Michael Faraday, forms the basis for the operation of generators, transformers, and many electrical devices. It describes how electrical energy can be generated from mechanical motion or changing magnetic fields.
Developers should understand electromagnetic induction when working on hardware-related projects, embedded systems, IoT devices, or renewable energy applications, as it explains how sensors, motors, and power systems function. It's crucial for designing circuits that involve inductive components like coils, transformers, or wireless charging systems, ensuring efficient energy transfer and signal processing.
