ProcirelInductive reactance is the opposition an inductor presents to alternating current (AC). Unlike capacitive reactance, it increases with frequency. Critical for designing LC filters, RF tuning circuits, impedance matching networks, and understanding motor and transformer behavior.

How to use this calculator
Step-by-Step Instructions
1. **Enter the AC frequency** in Hz.
2. **Enter the inductance** in millihenrys (mH). Convert µH to mH by dividing by 1000.
3. **Click Calculate** The inductive reactance is shown in Ohms.
Worked Example
100mH inductor at 1kHz: XL = 2π × 1000 × 0.1 = **628.32Ω**
