Magnetic components are essential parts used in electrical devices to manage and control magnetic fields. Common examples include inductors, transformers, and chokes. These components help in energy storage, voltage transformation, and filtering signals in various applications, from power supplies to audio equipment. These components work based on the principles of electromagnetism, where electric current creates a magnetic field. The design and materials used in magnetic components, such as ferrite cores or copper wire, significantly influence their efficiency and performance in electronic circuits.
