You might be considering magnetic locks to help secure your home, business, or government facility. At the same time, however, you find that you don’t understand how they actually work. Fortunately, we can help solve this mystery for you. Read on to learn more about the science and mechanics of magnetic locks.
Magnetic locks are more commonly called mag locks, so when you speak to professional locksmiths, you will soon pick up on that’s what the term is supposed to mean. An electromagnet is the main component, aligned with what is known an armature plate. The magnet is hidden inside the door itself, which means intruders will not be able to interfere with its operation. The magnet needs electricity to remain locked, but when all of the power inside a building goes out, the circuit is broken. Although you might think this means the magnetic lock stops working, it just ensures that the door will stay unlocked long enough to ensure everyone inside can evacuate to safety.
If you aren’t familiar with how electromagnetism is supposed to work, we don’t blame you. Electric currents run through special wiring that produces a small magnetic field. The pull is enough to hold the door in the locked position. Reinforcing the lock involves adding more of these wires. Part of a magnetic lock is a layer of iron to help increase the amount of pressure holding the lock closed. But the right magnetic strip on an access card will unlock the magnetic lock.
Instead of a standard key, magnetic locks typically require keycards to open. Other alternatives for releasing magnetic locks include a buzzer system – which are normally found in higher security areas such as commercial buildings, military installations, research labs, and prisons – and a keypad that needs the correct pass code. Ultimate security is available in the form of retinal scanners, fingerprint readers, and facial scans – all of which will open magnetic locks attached to the most sensitive restricted areas.
Using magnetic locks as the basis of your security system can help keep intruders out. Although it’s not as easy for someone to break these locks, locksmiths still need to know how to work with them. Likewise, all of your employees need to make sure they don’t lose their key cards or access credentials. Luckily, activating a new key card is much simpler and less time-consuming than having to cut an entirely new set of keys.
