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:
Where:
- is the magnetic capacitivity (SI Unit: -s·Ω-1)
- is the angular frequency of the magnetic circuit
In complex form it is written as an imaginary number:
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 capacitivity is a reactive part of the magnetic circuit.
Famous quotes containing the word magnetic:
“We are in great haste to construct a magnetic telegraph from Maine to Texas; but Maine and Texas, it may be, have nothing important to communicate.”
—Henry David Thoreau (1817–1862)
