The invention relates to a lifting magnet, in particular to an active lifting electric permanent magnet capable of automatically attracting and releasing. Comprising an electro-permanent magnet, a trigger device, a manual control panel and a lifting connecting part, a containing chamber is arranged on the upper portion of the electro-permanent magnet, an electrical control unit and an energy storage power source are arranged in the containing chamber, and the energy storage power source provides needed electric energy for the electrical control unit and the electro-permanent magnet; the triggering device is arranged at the top of the electro-permanent magnet, the lifting connecting part comprises a hanging bow, the two ends of the hanging bow are connected with the top of the electro-permanent magnet, and external triggering implementation is provided for the triggering device; the triggering device receives external triggering implementation and sends out a triggering signal; the electrical control unit receives the trigger signal, detects the magnetic characteristic state of the electro-permanent magnet, generates magnetic control current to the electro-permanent magnet, and changes the magnetic characteristic state of the electro-permanent magnet to enable the electro-permanent magnet to be in a lifting or releasing state; and magnetic poles are arranged on the bottom working surfaces of the electro-permanent magnets. The suction device is simple in structure, safe in suction force, convenient to repair and maintain and capable of automatically sucking and releasing materials.
