Quick Overview

An electromagnet is a type of magnet created by wrapping a coil of wire around a core material, typically made of iron or other ferromagnetic materials. When an electric current flows through the coil, it generates a magnetic field, which can be controlled and used for various applications.

How It Works

An electromagnet is a core component in electrical engineering that produces a magnetic field when an electric current flows through it. It consists of a coil of wire wound around a core material, often made of iron. When an electric current passes through the coil, it generates a magnetic field with a strength directly proportional to the current's magnitude. Unlike permanent magnets, electromagnets can be turned on and off by controlling the electric current. This feature makes them highly versatile and crucial in various applications, including electric relays, speakers, MRI machines, and even in the operation of many types of industrial machinery, where precise control of magnetic fields is necessary. Electromagnets are a foundational technology with widespread uses across different industries.
