Magnetic impedance (full magnetic resistance)is the scalar value, which is equal to the relation of effective or amplitude value of a sinusoidal magnetic tension on the passive magnetic circuit or its element and accordingly the effective or amplitude value of a sinusoidal magnetic current in this circuit or in this element.

Magnetic impedance [1-3] is measuring in units – [\frac{1}{\Omega}] and determining by the formula:

z_M = \frac{N}{I_M} = \frac{N_m}{I_{Mm}}

The full magnetic resistance (magnetic impedance) is equal

z_M = \sqrt{r_{M}^2 + x_{M}^2} , \phi = \arctan {\frac{x_M}{r_M}}

where rM = zMcosφ is the real part of the complex magnetic impedance, naming as the effective magnetic resistance;

xM = zMsinφ is the imaginary part of the complex magnetic impedance, naming as the reactive magnetic resistance.
