This blog post aims to explore the mainstream models of inductor functions and principles, providing a comprehensive understanding of their operation, construction, and applications. II. Basic Principles of Inductance A. Definition of Inductance Inductance is the property of an electrical conductor that opposes changes in current. It is measured in henries (H) and is defined as the ratio of the induced electromotive force (EMF) to the rate of change of current. When the current through an inductor changes, it generates a magnetic field that induces a voltage in the opposite direction, according to Lenz's Law. B. Faraday's Law of Electromagnetic Induction Faraday's Law states that a change in magnetic flux through a circuit induces an electromotive force (EMF) in that circuit. This principle is fundamental to the operation of inductors. 1. Explanation of Magnetic Fields When current flows through a wire, it creates a magnetic field around it. The strength of this magnetic field is proportional to the amount of current flowing through the wire. In inductors, this magnetic field is concentrated and controlled, allowing for efficient energy storage. 2. Induced Electromotive Force (EMF) The induced EMF in an inductor can be calculated using Faraday's Law, which states that the induced EMF (ε) is equal to the negative rate of change of magnetic flux (Φ) through the circuit: \[ ε = -\frac{dΦ}{dt} \] C.
