Magnetic Locks: How Do They Work?

Posted on November 11, 2010 by Jaece Hogue

Technology is changing the world at a steady but sure pace. This has been the norm for almost as long as humans have relied on technology for everyday goods and services. Computer processing speed is increasing while processor size continues to shrink. Advances in petroleum and energy technologies are allowing for safer, more efficient cars with cleaner operation. The parts of the vehicles that are seen traveling the highways these days are stronger and lighter than they were even five years ago. The advent of the Internet and digital communications ensure that we are as connected as we have ever been at any point in our history. Certain of these innovations tend to catch on after a while, and yet there are some that the public takes to like flies to honey. In all, technology works wonders if you allow it, but there is no standing in the way of progress.

The same goes for the locksmithing industry. The onset of mass production in the manufacturing industry allowed for locks to be made more cheaply and with interchangeable parts. Today we have electronic locks and even an entire sector of the security industry that deals everyday with data that does not physically exist. As the simple concept of a lock and key becomes more sophisticated, the job requirements and basic duties of the average locksmith become redefined. One such sophisticated form of security includes the magnetic lock. Introduced in 1989, the magnetic lock features an electromagnet set into the door frame and what is called an armature plate set into the door. When an electrical current is passed through the electromagnet the door is effectively locked. It is when the current is disrupted that access may be gained.

There are many advantages to using an electromagnetic lock as opposed to an ordinary lock-and-key setup. Because there are no interconnecting parts, the lock is generally easier to install and service than ordinary setups. Magnetic locks work very quickly during the power cycle of their operation. As well, it takes very little power, around 3 watts, to operate the lock. To put that in perspective, the average light bulb requires 60 watts to operate. However, the locks can be quite expensive and require a continuous power supply for continuous security.
