    "abstract": "The following inverse problem is discussed. A static electromagnetic field\ngenerated by a limited system of charges and currents is supposed to be known\nwith its first derivatives at a point somewhere far from the system. This\nallows to reconstruct the position of the system, its net charge, and the\nelectric and magnetic moments of the system.",
