This Wire Self-Inductance Calculator helps engineers compute the self-inductance of a straight wire based on its length and diameter.

Self-inductance is a critical parameter in designing circuits that involve inductive components, as it affects the wire’s ability to store energy in its magnetic field.

Why Use This Calculator?

Manually calculating the self-inductance of a wire involves complex formulas that depend on the wire’s geometry and material properties. This tool simplifies the process by:

How to Use the Wire Self-Inductance Calculator

1. Input Wire Length (L): Specify the length of the wire in meters.
2. Enter Wire Diameter (d): Provide the diameter of the wire in meters.
3. Click Calculate: Get the self-inductance value in microhenries (µH).

Formula

The self-inductance Ls​ of a straight wire is given by the following formula:

Where:

• Ls​: Self-inductance (Henries)
• $L$: Length of the wire (meters)
• d: Diameter of the wire (meters)
• $\ln$: Natural logarithm

This formula assumes the wire is in free space and sufficiently long compared to its diameter.

Applications of Wire Self-Inductance

Self-inductance is a fundamental concept in electrical engineering, with applications including:

1. High-Frequency Circuit Design: Understanding parasitic inductance in conductors.
2. Transformers and Inductors: Calculating the inductance of primary and secondary windings.
3. Power Transmission: Evaluating inductive effects in long transmission lines.
4. RF Design: Determining inductive behavior of conductors in radio frequency systems.

This calculator is a must-have tool for engineers working on designing and optimizing electrical systems involving wires and inductive components.
