Inductance

प्रेरकत्व

In this Class 12 Physics topic from Electromagnetic Induction, students learn how inductance describes a coil’s ability to oppose changes in current by producing an induced emf. The topic introduces self-inductance and mutual inductance, explains their dependence on factors such as the number of turns, coil geometry, and magnetic permeability, and develops the related formulas and SI unit, the henry. Students also study energy stored in an inductor and its role in electrical circuits and electromagnetic devices.
