Inductance of a Helmholtz coil pair?

    Hello * -

    I have found a number of web sites that detail both theoretical and
    practical treatments of Helmholtz coil pairs. Some deal with the
    subject in excruciating detail, most show curves detailing
    calculations or measurements of the vector B-field within the coil

    I am trying to calculate the inductance of a Helmholtz coil pair.

    It seems this should be treated as a pair of air-coupled coils.. which
    means the mutual inductance needs to be calculated. I have an
    expression for the inductance of a multi-layer multi-turn solenoid..
    but the expression for the mutual inductance eludes me.

    Suggestions, guidance, and/or pointers to sources of information would
    be appreciated.
