RE: [femm] eddy-curr in a tube

["McGee" <mcgee@xxxxxxxxxxxxxxxxxx>]

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.
