Magnetic impedance (SI Unit: -Ω-1) is the ratio of a sinusoidal magnetic tension Nm to a sinusoidal magnetic current IMm in a gyrator-capacitor model. Analogous to electrical impedance, magnetic impedance is likewise a complex variable.
Magnetic impedance is also called the full magnetic resistance. It is derived from:
- rM = zMcosφ, the effective magnetic resistance (real)
- xM = zMsinφ, the reactive magnetic resistance (imaginary)
The phase angle φ of the magnetic impedance is equal to:
