Magnetic effective resistance (SI Unit: -Ω⁻¹) is the real component of complex magnetic impedance of a circuit in the gyrator-capacitor model. This causes a magnetic circuit to lose magnetic potential energy.^[1][2][3]

Active power in a magnetic circuit equals the product of magnetic effective resistance r_M and magnetic current squared $I_{M}^2$.

$P = r_M I_{M}^2$

The magnetic effective resistance on a complex plane appears as the side of the resistance triangle for magnetic circuit of an alternating current. The effective magnetic resistance is bounding with the effective magnetic conductance g_M by the expression

$g_M = \frac{r_M}{z_{M}^2}$

where z_M is the full magnetic impedance of a magnetic circuit.
