Electromagnetic Door Lock

An electromagnetic door lock utilizes an electromagnet to open and close a door. It is usually used in areas where high security is needed, such as banks and offices. These locks use an electric current to produce a magnetic field, which when energized, can keep the door locked. When the current is disengaged, the magnetic field is no longer created and the door is unlocked. It is often used in combination with other locks, such as a PIN pad, biometric reader, card reader, or key pad.
