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 rM 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 gM by the expression

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

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