Magnetic impedance - Alchetron, The Free Social Encyclopedia

Magnetic impedance (SI Unit: -Ω⁻¹) is the ratio of a sinusoidal magnetic tension N m to a sinusoidal magnetic current I M m in a gyrator-capacitor model. Analogous to electrical impedance, magnetic impedance is likewise a complex variable.

z M = N I M = N m I M m

Magnetic impedance is also called the full magnetic resistance. It is derived from:

r M = z M cos ⁡ ϕ , the effective magnetic resistance (real) x M = z M sin ⁡ ϕ , the reactive magnetic resistance (imaginary)

The phase angle ϕ of the magnetic impedance is equal to:

ϕ = arctan ⁡ x M r M
