Door suction semi-circular magnet is a common magnet device, usually used in door locks or access control systems. It is made of a powerful neodymium magnet, in a semi-circular shape, and attached to a metal plate or base.
The working principle of the door magnet is to use magnetic attraction to keep the door closed. It usually consists of two parts: a metal plate mounted on the door frame, and a magnet mounted on the door. When the door is closed, there is a magnetic attraction between the magnet and the metal plate, keeping the door tightly in the closed position and preventing the door from opening on its own.
This type of magnet usually has a high magnetic and holding power to ensure that the door remains firmly closed. They are commonly used in places that require high safety and reliability, such as commercial buildings, public institutions, and medical institutions.
