Magnetic capacitivity (SI Unit: H) is a component used in the gyrator-capacitor model of magnetic systems.
This element, denoted as CM, is an extensive property and is defined as:
Where: μrμ0 = μ is the magnetic permeability, S, l is the cross-section and the length of the element.
For phasor analysis, the magnetic permeability[1] and the magnetic capacitivity are complex values[1, 2].
Magnetic capacitivity is also equal to magnetic flux divided by the difference of magnetic potential across the element.
Where:
- φM1 − φM2 is the difference of the magnetic potentials.
The notion of magnetic capacitivity is employed in the gyrator-capacitor model in a way analogous to capacitance in electrical circuits.
