sci.maxwell-inductance-solenoid Calculator
Calculates solenoid inductance L = µ₀N²A/l and magnetic field B = µ₀nI, where n is turns per unit length. A 100-turn solenoid (l = 10 cm, A = 1 cm²) has L = 12.6 µH — toroidal geometry eliminates external leakage flux, giving higher effective inductance for the same winding.
Inputs
N Turns
Count of items or occurrences.
R Cm
Distance from centre to edge of a circle. Radius = diameter / 2.
L Cm
Linear measurement. Ensure consistent units: 1 m = 1,000 mm = 3.281 ft.
Mu R
Reference formula or conversion factor shown for context.
Results
inductance L (H)
Sample size or count used in the calculation.
inductance L (mH)
Sample size or count used in the calculation.
inductive reactance XL at 1 kHz (Ω)
The value at the specified point or condition.
L = μ₀μr·N²·A/l
Sample size or count used in the calculation.
aspect ratio l/2r
The proportional relationship between two quantities.
