Abstract
The tangential and normal components of a dipole force acting upon a neutral spherical particle moving parallel to the axis of symmetry of a coaxial cylindrical channel with different permittivities of the internal and external walls are calculated in a nonrelativistic approximation of the fluctuational electromagnetic theory. Upon a limiting transition, the obtained formulas coincide with the previous results for a particle moving inside a cylindrical channel or parallel to the generatrix of a convex cylindrical surface. The problem is considered in the general case of different temperatures of the particle and the surface.
