What's the difference between inductance and reactance of an inductor

Inductance is a physical property of the coil or conductor, units in Henries, and is independent of the frequency of the signal in the component.

Reactance, in units of Ohms, is dependent on the frequency of the signal.
The formula for reactance is:

XL = 2 x pi x f x L

where
f = frequency (Hz)
L = inductance (H)

 

Reactance is the Resistive property in Ohms, when an AC signal is passed through it, the inductor behaves like a resistor and increases its reactance with frequency increase and vice-versa.


The formula is 6.284 x F x L = Ohms.

 

And a Inductance is expressed in Henry's or MicroHenry.
It is characterized as where the current is changing at a constant rate of one ampere per second , an inductance of 1 H results in the generation of one volt (1 V) of potential difference across an inductor.
This remains a constant for a particular inductive device.
As opposed to reactance or impedance in ohms where the value changes with frequency.
Max.

 

Reactance is the Resistive property in Ohms, when an AC signal is passed through it, the inductor behaves like a resistor

That's a little misleading.
It's more accurate to say it has an impedance in ohms.
It's different from the resistance of a resistor in that it adds a 90° phase-shift between the voltage across it and the current through it.
