What Industries Do Fixed Inductor Application Scenarios Include?
I. Introduction
In the realm of electronics, fixed inductors play a crucial role in the functionality and efficiency of various devices. A fixed inductor is a passive electronic component that stores energy in a magnetic field when electrical current flows through it. Unlike variable inductors, which can change their inductance value, fixed inductors have a set inductance value determined by their physical characteristics. This blog post aims to explore the significance of fixed inductors across multiple industries, highlighting their applications and the impact they have on modern technology.
II. Understanding Fixed Inductors
A. Basic Principles of Inductance
Inductance is the property of an electrical conductor that opposes changes in current. When current flows through a coil of wire, it generates a magnetic field around it. This magnetic field can induce a voltage in the coil itself or in nearby conductors, a phenomenon known as electromagnetic induction. Fixed inductors utilize this principle to store energy and regulate current flow in electronic circuits.
