EEE117 Lecture 4: Magnetic Circuits & Inductive Electric Circuit Models

The flux linkage is the flux multiplied by the number of turns, N, of the coil.

The induced emf is calculated using Faraday's law.

Self-inductance is defined as the property of a coil with N turns to store energy in the form of magnetic field.
