The eddy current lossesP in a conducting hollow circular cylinder slowly rotating in a homogeneous magnetic field perpendicular to its axis are calculated for an arbitrary lengthl and an arbitrary ratio λ of the inner and outer cylinder radii. The results allow an electrodeless resistivity determination of such samples by torque measurements. To facilitate this and other applications, simple approximations forP(l) are given for a set of λ-values.
