Magnetic capacitance

Magnetic capacitance (capacitive magnetic reactance) (SI Unit: -Ω⁻¹) is a magnetic "reactance" which prevents magnetic "current" in oscillating magnetic circuits from rising. This is associated with high reluctance.

For harmonic regimes it is equal to:

x_{C}={\frac {1}{\omega C_{M}}}

Where:

C_M

is the magnetic capacitivity (SI Unit: -s·Ω⁻¹)

\omega

is the angular frequency of the magnetic circuit

In complex form it is written as an imaginary number:

-jx_{C}=-j{\frac {1}{\omega C_{M}}}={\frac {1}{j\omega C_{M}}}

The electrical potential energy sustained by magnetic capacitivity varies with the frequency of oscillations in magnetic fields. The average power in a given period is equal to zero. The magnetic capacitance is a reactive part of the magnetic circuit.^[1]^[2]
