Transposition of formula(inductance)

  1. Sep 25, 2006 #1
    Hi i hope you can help me?
    My question is:

    Given the relationships:

    B/h = U, H = IN/l and L = N x dphi/dI {ie, L = N x change in phi/change in I}.

    show that the inductance of the coil is:

    L = Nsquared/S Where S = l/uA ????????????

    .l is lower case L for length
    .U is absolute permeability.
    your help would be most welcome please many thanks

    Have you got any ideas on how you might find the equation for the inductance of a solenoid?
