Inductance is the tendency of an electrical conductor to oppose a change in the electric current flowing through it. The electric current produces a magnetic field around the conductor. The magnetic field strength depends on the magnitude of the electric current, and follows any changes in the magnitude of the current.
This tool is designed to calculate the inductance of a coil of wire given the length of the coil, the number of turns, the loop radius, and the permeability of the core material.
This single-layer coil inductance calculator is an interactive online tool specifically designed to calculate the inductance value of a single coil of thin round-wire based on the coils loop inductance value.
This reference shows the inductance of many different coil shapes such as single-turn loops, rectangles, multiple-layer coils, and solenoids of various lengths. The Dwight reference [7] is very useful for calculating high-frequency effects in inductors, and covers skin and proximity effects.
This article describes the inductance formula and how to calculate inductance. When electric current flows through the inductor, a magnetic field is produced around it. The strength of the magnetic field depends on the inductance, current, and number of turns in a coil.
EEWeb have a free online Coil Inductance Calculator for calculating the inductance of a coil for different configurations of wire size and positioning. As well as increasing the number of coil turns, we can also increase inductance by increasing the coils diameter or making the core longer.
Calculate the inductance of an inductor. Calculate the energy stored in an inductor. Calculate the emf generated in an inductor. Inductors. Induction is the process in which an emf is induced by changing magnetic flux. Many examples have been discussed so far, some more effective than others.
A circuit with a self inductance of one henry will experience a back emf of one volt when the current changes at a rate of one ampère per second. Inductance is the resistance of a circuit element to changes in current. Inductance in a circuit is the analog of mass in a mechanical system.
Inductance is the property of a device that expresses how effectively it induces an emf in another device. Mutual inductance is the effect of two devices inducing emfs in each other. A change in current \(\displaystyle dI_1/dt\) in one circuit induces an emf (\(\displaystyle ε_2\)) in the second:
Inductance is the ability of a structure to store energy in a magnetic field. The inductance of a structure depends on the geometry of its current-bearing structures and the permeability of the intervening medium. Note that inductance does not depend on current, which we view as either a stimulus or response from this point of view. The ...
