Does inductive reactance increase with frequency?
Yes. In the ideal relation, reactance is directly proportional to frequency.

Inductive Reactance Calculator — XL from Frequency & Inductance
Calculate ideal inductor reactance from frequency and inductance with Hz/kHz and H/mH/µH input units.
Result
31.415927 Ω
50 Hz · 0.1 H
X_L = 2πfL
Formula and worked example
X_L = 2πfL.
At 50 Hz, a 0.1 H ideal inductor has about 31.416 Ω of inductive reactance.
Assumptions
- The calculation uses the ideal sinusoidal steady-state relation.
- Winding resistance, core loss, saturation and parasitic capacitance are not included.

Frequently asked questions
Is reactance the same as resistance?
No. Both are measured in ohms, but reactance is the frequency-dependent opposition associated with energy storage.
