Self-inductance is a property of an electrical circuit or coil that describes its ability to induce an electromotive force (emf) in itself due to a change in the current flowing through it. This phenomenon arises from the magnetic field generated by the current, which can create an opposing voltage when the current changes, thus resisting the change. Understanding self-inductance is crucial as it relates to motional emf, mutual inductance with other coils, and the behavior of RL circuits during transient states.
congrats on reading the definition of self-inductance. now let's actually learn it.
