Quantum topological phase of an electric dipole circulating around a ferromagnetic wire

The quantum topological phase of electric dipole circulating around the line of magnetic charges (monopoles) is discussed. We propose to mimic the line of magnetic monopoles using a ferromagnetic wire in which the magnetization is parallel to the wire and the magnitude of magnetization changes linearly along the wire. The phase shift in the proposed scheme is within the reach of present experimental techniques and may be observed in atomic or molecular interferometry.
