Understanding Inductance Inductance is a fundamental concept in electromagnetism and plays a crucial role in electrical circuits. It refers to the property of an electric circuit that causes a change in current to induce an electromotive force (EMF). The unit of inductance is the henry (H). When current flows through a conductor, it generates a
Motional Electromotive Force The concept of motional electromotive force (emf) plays a crucial role in the field of electromagnetism and electricity generation. It refers to the induced emf that occurs when a conductor, such as a wire, moves through a magnetic field. Understanding this phenomenon is essential for grasping how electrical energy can be generated
