A remanence-eliminating magnetic lock, comprising: a housing provided with a receiving space therein; an electromagnetic body configured to be assembled within the receiving space of the housing with a top surface of the electromagnetic body being exposed from the housing, receive externally supplied electricity, and generate a magnetic attraction force on the top surface of the electromagnetic body; and a resilient abutting member at least having: a fixing end configured to be fixed within the housing or the electromagnetic body; and an abutting end configured to be exposed from the housing or the top surface of the electromagnetic body with a peak of the abutting end being at a higher elevation than the top surface of the electromagnetic body, when the magnetic lock is supplied with electricity and a metal member is magnetically attracted and attached to the top surface of the electromagnetic body, deform by being pressured by the metal member and generate a restoring force, and when the supply of the electricity to the magnetic lock is cut off, push the metal member, through the restoring force, to move the metal member away from the top surface of the electromagnetic body to eliminate remanence, the remanence-eliminating magnetic lock being characterized in that: the resilient abutting member is a flat body and in a shape of an inverted letter J, and a top end section of the resilient abutting member is bent to form the abutting end. a housing provided with a receiving space therein; an electromagnetic body configured to be assembled within the receiving space of the housing with a top surface of the electromagnetic body being exposed from the housing, receive externally supplied electricity, and generate a magnetic attraction force on the top surface of the electromagnetic body; and a resilient abutting member at least having: a fixing end configured to be fixed within the housing or the electromagnetic body; and an abutting end configured to be exposed from the housing or the top surface of the electromagnetic body with a peak of the abutting end being at a higher elevation than the top surface of the electromagnetic body, when the magnetic lock is supplied with electricity and a metal member is magnetically attracted and attached to the top surface of the electromagnetic body, deform by being pressured by the metal member and generate a restoring force, and when the supply of the electricity to the magnetic lock is cut off, push the metal member, through the restoring force, to move the metal member away from the top surface of the electromagnetic body to eliminate remanence, a fixing end configured to be fixed within the housing or the electromagnetic body; and an abutting end configured to be exposed from the housing or the top surface of the electromagnetic body with a peak of the abutting end being at a higher elevation than the top surface of the electromagnetic body, when the magnetic lock is supplied with electricity and a metal member is magnetically attracted and attached to the top surface of the electromagnetic body, deform by being pressured by the metal member and generate a restoring force, and when the supply of the electricity to the magnetic lock is cut off, push the metal member, through the restoring force, to move the metal member away from the top surface of the electromagnetic body to eliminate remanence, the remanence-eliminating magnetic lock being characterized in that: the resilient abutting member is a flat body and in a shape of an inverted letter J, and a top end section of the resilient abutting member is bent to form the abutting end.
