Self & Mutual Inductance: Self-inductance (L) is the property of an electrical circuit (typically a coil) to oppose changes in the current flowing through itself. When the current in a coil changes, it creates a changing magnetic field that induces an opposing electromotive force (EMF) within the same coil. This phenomenon is crucial for inductors used in various electronic circuits. Mutual inductance (M) describes the phenomenon where a changing current in one coil induces an EMF in a nearby, separate coil. This occurs because the magnetic field produced by the first coil links with the second coil. Mutual inductance is the operating principle behind devices like transformers. Both self and mutual inductance are measured in Henrys (H).
