Phasor Magnetic Circuits
Gyrator-capacitor model variables
- 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 gyrator-capacitor model for magnetic systems.
For phasor analysis the magnetic inductive reactance is:
- xL = ωLM
In the complex form it is a positive imaginary number:
- jxL = jωLM
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 gyrator-capacitor model in a way analogous to inductance in electrical circuits.
