Magnetic impedance : ウィキペディア英語版
Magnetic impedance

Magnetic impedance (SI Unit: -Ω−1) is the ratio of a sinusoidal magnetic tension N_\mathrm to a sinusoidal magnetic current I_\mathrm in a gyrator-capacitor model. Analogous to electrical impedance, magnetic impedance is likewise a complex variable.
:z_\mathrm = \frac} = z_\mathrm \cos \phi, the effective magnetic resistance (real)
:x_\mathrm = z_\mathrm \sin \phi, the reactive magnetic resistance (imaginary)
The phase angle \phi of the magnetic impedance is equal to:
:\phi = \arctan }}
