The invention provides a magnetic track brake electromagnet and a magnetic track brake. According to the magnetic track braking electromagnet, the magnet exciting coil is arranged on the electromagnetic iron core, so that a track can be braked by a magnetic track brake through power-on attraction; the electromagnetic iron core is arranged on the frame body, so that the electromagnetic iron core can be conveniently mounted and connected with other structures of the magnetic track brake; the excitation coil is wrapped by the insulating protective layer, so that the excitation coil can be prevented from being influenced by an external magnetic field, and the stability of the track during attraction is improved; by arranging the sealing layer to cover the insulating protection layer, damage to the insulating protection layer caused by external impurities can be avoided, and the working stability of the magnetic track brake is effectively improved; according to the magnetic track brake, the first heat insulation layer is arranged between the sealing layer and the insulation protection layer and corresponds to the welding position of the sealing layer and the frame body, the influence of welding heat and impurities on the insulation protection layer can be effectively reduced, the insulativity and the power frequency pressure resistance of the magnetic track brake are guaranteed, and meanwhile the sealing effect of the sealing layer on the insulation protection layer is guaranteed.
