Inductor Calculator

Inductor Calculator — Calculate Inductance, Impedance & Energy

Calculate inductance, inductive reactance, energy storage, and winding parameters for air-core and ferrite-core inductors.

Step 1: Inductor Specifications

Inductance (L)

µH

100 µH

Frequency (f)

kHz

1,000 kHz

Current (I)

1 A

Inductor Core Types

Air-core: Simple, no core loss, lower inductance. Ferrite-core: Higher inductance, core losses at high frequencies. Iron-core: Highest inductance, significant core losses.

Step 2: Physical Parameters

Core Material

Number of Turns (N)

turns

50 turns

Coil Diameter

10 mm

Include wire length calculation

Calculate quality factor (Q)

Physical Parameters

Inductance increases with more turns, larger coil diameter, and higher core permeability. Wire length ≈ π × diameter × turns. Q-factor depends on frequency and core losses.

Inductor Equations

X_L = 2πfL E = ½LI² L = μ₀μ_rN²A/l

Inductive reactance (X_L) = 2π × frequency × inductance. Stored energy (E) = ½ × inductance × current². Inductance depends on core permeability (μ), turns (N), cross-sectional area (A), and length (l).
