An electromagnet door lock is provided to prevent an erroneous operation of the door lock by using an electromagnet to lock the door lock according to an electrical signal. A door lock body(100) includes an electromagnet core, a controller, a housing and a cover. An installation plate(200) fixes the door lock body on a door frame or a wall. Plural small bumps and a magnetic force canceling unit are formed on a surface corresponding to the electromagnet core of the door lock body. An armature plate(300) includes a coupling hole and a permanent magnet(313). A bonding hole is formed at a center of a first bracket(400), such that the first bracket is bonded with the coupling hole of the armature plate using a coupling member. An upper surface of a second bracket(500) is coupled with a lower surface of the first bracket. A side portion of the second bracket is fixed on the door.
