The measurement of the top-quark anomalous electromagnetic couplings is one of the most important goals of the top-quark physics program in present and future collider experiments and would provide direct information on the non-standard interactions of the top quark. We study a top-quark pair production scenario at the Future Circular Collider Hadron-Electron (FCC-he) through
