 Magnetic inductance is not to be confused with "Magnetic induction", which usually refers to Magnetic field.
Magnetic inductance (inductive magnetic reactance) (SI Unit: Ω^{−1}) is a component in the gyratorcapacitor model for magnetic systems.
For phasor analysis the magnetic inductive reactance is:
 x_{L} = ωL_{M}
Where:
 L_{M} is the magnetic inductivity (SI Unit: s·Ω^{1})
 ω is the angular frequency of the magnetic circuit
In the complex form it is a positive imaginary number:
 jx_{L} = jωL_{M}
The magnetic potential energy sustained by magnetic inductivity varies with the frequency of oscillations in electric fields. The average power in a given period is equal to zero. Due to its dependence on frequency, magnetic inductance is mainly observable in magnetic circuits which operate at VHF and/or UHF frequencies.
The notion of magnetic inductivity is employed in analysis and computation of circuit behavior in the gyratorcapacitor model in a way analogous to inductance in electrical circuits.
