    In his thesis, Trent Loga developed analytical solutions to confirm his FEM.
    Hope this helps.

    Hi, femm-friends

    I have a tube of finite length=2L, inner-radius=b,
    outer radius=a, relative mag. perm.=mur,
    el. conductivity=sigma.
    An infinite alternating current line Io.exp(jwt) is positioned
    (1) on the axis of the tube;
    (2) parallel to the axis, out at a distance c<b (inside).
    Do you know if any analytical solutions for eddy currents
    in the tube exist to compare with FEMM analysis?
    Thank you in advance Roberto.
