  1. reluctivitynoun

    The quantity equal to the reciprocal of magnetic permeability.


  1. reluctivity

    Magnetic reluctance, or magnetic resistance, is a concept used in the analysis of magnetic circuits. It is defined as the ratio of magnetomotive force (mmf) to magnetic flux. It represents the opposition to magnetic flux, and depends on the geometry and composition of an object. Magnetic reluctance in a magnetic circuit is analogous to electrical resistance in an electrical circuit in that resistance is a measure of the opposition to the electric current. The definition of magnetic reluctance is analogous to Ohm's law in this respect. However, magnetic flux passing through a reluctance does not give rise to dissipation of heat as it does for current through a resistance. Thus, the analogy cannot be used for modelling energy flow in systems where energy crosses between the magnetic and electrical domains. An alternative analogy to the reluctance model which does correctly represent energy flows is the gyrator–capacitor model. Magnetic reluctance is a scalar extensive quantity. The unit for magnetic reluctance is inverse henry, H−1.


  1. reluctivity

    Reluctivity is a property of a material that quantifies how strongly it resists the formation of a magnetic field within itself. It is the reciprocal of magnetic permeability and is also sometimes referred to as specific magnetic reluctance. In simple terms, it measures the ability of a material to oppose the creation of the magnetic field within it.

The Standard Electrical Dictionary

  1. Reluctivity

    Specific reluctance; the reluctance of a cube of material whose edge measures one centimeter in length. It is a quality bearing the same relation to reluctance that permeability does to permeance. It is defined as the reciprocal of magnetic permeability. (Kenelly.) If plotted as a curve for different values of the magnetizing force it is found to be nearly a straight line, a linear function of the magnetizing force, H with the equation a + b H. Reluctivity is the property of a substance; reluctance is the property of a circuit.
