Precision tool for inductance, turns, and wire length calculations
Formula for air core solenoid:
L = μ₀ × N² × π × r² / l
Where μ₀ = 4π × 10⁻⁷ H/m (permeability of free space)
With core: L_core = μᵣ × L_air
Formula for air core solenoid:
N = √(L × l / (μ₀ × π × r²))
Where μ₀ = 4π × 10⁻⁷ H/m (permeability of free space)
With core: N_core = N_air / √μᵣ
Formula used:
Length per turn ≈ 2 × π × r
Total length ≈ N × 2 × π × r
Resistance ≈ ρ × (Total length) / (π × (d/2)²)
Where ρ = 1.68×10⁻⁸ Ω·m (copper resistivity)
