The two main types of induction are:
These two types of induction are fundamental concepts in electrical engineering and help explain a variety of electrical phenomena and technologies.
- Electromagnetic Induction: This is the process by which a change in the magnetic field within a closed loop of wire induces an electric current in that wire. The basic principle was discovered by Michael Faraday. Electromagnetic induction is the working principle behind devices like electric generators and transformers. In simple terms, when a magnetic field around a conductor (like a wire) changes, it creates an electric current in the conductor.
- Electrostatic Induction: This occurs when a charged object induces a charge distribution in a nearby neutral object, without direct contact. For example, when you bring a negatively charged rod close to a metal object, the charges in the metal rearrange themselves, with positive charges moving closer to the rod and negative charges moving away. This is called induction because it happens due to the presence of the charged object, but no current flows.
