When it comes to access control devices, safety is the most important thing. Magnetic locks, or maglocks, provide users with one of the safest and most durable locking solutions. They are a common way to ensure that gates and door locks for commercial buildings are safe. These locks have a strong and reliable locking system using electromagnetism. In this blog post, we go deep into the world of magnetic locks. We will look at what parts they have, how they work, and what they are good for. 

What Magnetic Locks Are Made Of

Magnetic locks comprise three basic parts: an electromagnet, an armature plate, and a power source. Let us look more closely at each:


The electromagnet is the heart of the magnetic lock. It is on the door frame. It is made up of a coil of wire wrapped around a metal core, which is usually made of iron or steel. An electric current that runs through the coil creates a magnetic field. It turns the electrical energy into a magnetic force.

Armature Plate

The electromagnet works with the armature plate on the door. It is made of a ferrous element like iron or steel, so it is drawn to the electromagnet’s magnetic field. When the door is closed, the armature plate is close to the electromagnet, with both sides facing each other.

Power Supply

The magnetic lock needs a power source to work. Usually, it uses a low-voltage DC power source, such as a transformer. This power source provides the electrical power that the electromagnet needs to work.

How Do Magnetic Locks Work?

It is easy to figure out how magnetic locks work. Let us go through each step of the process.


An electrical current runs through the electromagnet’s coil when the power source is on. This current creates a magnetic field around the electromagnet. Because it is made of iron, the magnetic field strongly draws the armature plate. The magnetic force between the electromagnet and the armature plate locks the door firmly. The size and power of the electromagnet affect how strong the magnetic pull is.


The power source stops the electric current flowing through the electromagnet to open the door. As a result, the magnetic field weakens, letting go of its hold on the armature plate. At this point, you can open the door easily now that the magnetic force is gone. Usually, you can unlock a magnetic lock using a control device, like a keypad, card reader, or biometric scanner, to cut off the power source to the lock.

Benefits of Magnetic Locks

Magnetic locks have several benefits that make them popular in access control systems.


Because they do not have any moving parts, magnetic locks are reliable. That means you do not have to worry about parts that can go wrong or tampered with. Plus, they have a strong locking system that lasts long and hardly ever needs fixing.

Strong Holding Force 

Because they create strong magnetic fields, magnetic locks have strong holding forces that make them hard to break into.


Magnetic locks are a great way to add extra security to your home. They can secure wood, glass, and metal doors and gates.

Fast Locking and Unlocking

You can quickly lock and unlock magnetic locks, which makes them suitable for controlling entry.

Integration with Access Control Systems

Magnetic locks work well with access control systems. They let you handle multiple doors from one place and let people in or keep them out depending on what you have programmed.

Keep Your Business Safe

Because they use electromagnetism, magnetic locks are a safe and effective way to control entry. To understand how they keep doors and gates safe, we must learn about their parts and how they work. These locks are a good choice for security in many places because they are reliable, have a strong holding force, and work with access control systems.
