Proximity effect between a wire carrying current and a rotating cylindrical conductor

The general expressions of the quasistationary electromagnetic field quantities, as well as the power loss, forces and torque, for a rotating cylindrical conductor in the proximity of a parallel straight wire carrying AC or DC, have been obtained by means of the magnetic vector potential, assuming a two-dimensional field. Specific motional field effects are shown explicitly in the DC case, when proximity factors and practical formulas of the losses, forces and torque are derived for values of motional depth of penetration large or small compared with the cylinder radius.
