Maglocks, or magnetic locks, are security devices that use electromagnetism to secure doors. When powered, a strong magnet holds the door closed, making it difficult to open without the correct access method. They are commonly used in commercial buildings and high-security areas. These locks typically require a power source and are often paired with access control systems, such as keycards or keypads. When the access method is used, the power is cut, allowing the door to open. Maglocks are valued for their strength and reliability, providing a secure solution for various entry points in buildings.
