    Reluctance is obtained by dividing the length of the magnetic path l by the permeability times the cross-sectional area A; thus r = l/μA, the Greek letter mu, μ, symbolizing the… Read More. In magnetic circuit. The reluctance r of a magnetic circuit is analogous to the resistance of an electric circuit.

    The ter m \(l/(\mu A)\) i s the reluctance, expressed in H-1. Reluctances add in series. The reciprocal of the reluctance is the permeance, expressed in H. Permeances add in parallel. Although the SI unit of permeance is the henry, permeance is not the same as the inductance.

    is the reluctance in ampere-turns per weber (a unit that is equivalent to turns per henry) is the magnetomotive force (MMF) in ampere-turns Φ is the magnetic flux in webers. It is sometimes known as Hopkinson's law and is analogous to Ohm's Law with resistance replaced by reluctance, voltage by MMF and current by magnetic flux.

    May 23, 2024 · As reluctance (S) is defined as the ratio of the magnetomotive force (MMF) to the magnetic flux (Φ) in a magnetic circuit: Reluctance (S) = MMF / Φ The unit of MMF is Ampere-turns (A-turn), and the unit of magnetic flux is Weber (Wb).

    Magnetic complex reluctance (SI Unit: H −1) is a measurement of a passive magnetic circuit (or element within that circuit) dependent on sinusoidal magnetomotive force (SI Unit: At·Wb −1) and sinusoidal magnetic flux (SI Unit: T·m 2), and this is determined by deriving the ratio of their complex effective amplitudes.[Ref. 1-3]
