Our Inductance of Wire Calculator helps you quickly determine the inductance (L) of a single-layer air-core coil or solenoid. Ideal for engineers, students, and DIY enthusiasts, this tool simplifies complex calculations. Understand how coil turns, diameter, and length affect inductance for various electrical and electronic applications.
Formula:
The inductance (L) of a single-layer air-core solenoid can be approximated by the formula:L = (μ₀ * N² * π * r²) / l
Where:
- L = Inductance (Henries)
- μ₀ = Permeability of free space (approximately 4π × 10⁻⁷ H/m)
- N = Number of turns in the coil (dimensionless)
- r = Radius of the coil (meters)
- l = Length of the coil (meters)
