Magnetic type electromagnet capable of automatically resetting in case of power failure

The invention relates to the technical field of electromagnets, in particular to a magnetic attraction type electromagnet capable of automatically resetting in power failure, which comprises a shell, a hollow framework, a movable core attraction coil, a suction cup coil, a suction cup magnet, a movable iron core and a reset spring, the movable core attraction coil and the suction cup coil are sleeved on the hollow framework, and the hollow framework is embedded in the shell; the sucker magnet is embedded in the shell, the movable iron core is inserted into the hollow framework, and the reset spring is sleeved on the periphery of the movable iron core. The electromagnet generates a forward induced magnetic field after the upper-section movable core attraction coil is electrified, the movable iron core is driven to move downwards, the lower end of the movable iron core is in contact with the suction cup magnet, and then the suction cup coil is electrified to enable the suction cup magnet to generate magnetic at
