Defined as passive electronic components that store energy in a magnetic field when electrical current flows through them, inductors are essential in various applications, from power supplies to radio frequency (RF) circuits. Understanding the product characteristics of inductors is vital for engineers and designers to select the right component for their specific needs. This blog post will delve into the basic principles of inductance, key product characteristics, types of inductors, and their applications. II. Basic Principles of Inductance A. Definition of Inductance Inductance is the property of an electrical conductor that opposes a change 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 flowing through an inductor changes, it generates a magnetic field that induces a voltage in the opposite direction, according to Lenz's Law. B. The Role of Magnetic Fields The magnetic field generated by an inductor is a key aspect of its functionality. When current flows through the coil of wire that makes up the inductor, a magnetic field is created around it. This magnetic field stores energy, which can be released back into the circuit when the current decreases. The strength of the magnetic field is directly proportional to the amount of current flowing through the inductor. C. 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, as it explains how they can store and release energy.
