Electromagnetic Lock

The working principle of the Magnetic Lock

The design of the magnetic lock (or electromagnetic lock) is the same as that of the electromagnet. It uses the principle of electromagnetism. When the electric current passes through the silicon steel plate, the electromagnetic lock will generate powerful magnetism and tightly attract the iron plate to lock the door. As long as a small electric current electromagnetic lock will generate a powerful magnetic force, the access control system that controls the power supply of the electromagnetic lock will cut off the power after identifying the authorized users and the electromagnetic lock can open the door after power off. This is Fail-Safe locks.

We know that every magnet has two poles, a north pole (N pole) and a south pole (S pole). Magnets have the characteristics of repulsion of the same points and attraction of opposite point, Magnetic locks take advantage of this feature of magnets. The unlocking tools made of permanent magnets (magnetic beads) are also called "electronic locks".
