Disclosed is an electrically-controlled magnetic connecting device. The electrically-controlled magnetic connecting device comprises: an electric motor (10); a first magnet (20) disposed on a housing of the electrically-controlled magnetic connecting device; and a second magnet (30) disposed beside the first magnet (20) and capable of rotating with respect to the first magnet (20) by means of the electric motor (10), so that relative positions of magnetic poles of the first magnet (20) and the second magnet (30) change. The electrically-controlled magnetic connecting device comprises an on state and an off state. In the on state, the magnetic poles at the same side of the first magnet (20) and the second magnet (30) are the same to produce an attraction force for a ferromagnetic object; and in the off state, the magnetic poles at the same side of the first magnet (20) and the second magnet (30) are opposite to release the attraction force for the ferromagnetic object. The electrically-controlled magnetic connecting device can be automatically and remotely controlled.
