Neodymium magnets – strong features for FIDLOCK fasteners

Neodymium magnets – strong features for FIDLOCK fasteners

All FIDLOCK magnetic fasteners are based on the unique FIDLOCK concept which combines a mechanical lock with magnetic attraction. As a result, FIDLOCK fasteners revolutionized conventional fastening alternatives, revealing new dimensions in ease of use, functionality and fun. Key to many perks of these fasteners and buckles are the neodymium magnets – but why exactly and what makes them so special?

Strongly attracted to each other

Typical for FIDLOCK fasteners are secure hold, automatic closure and single-handed operation – features that don’t coincide naturally. This is where the FIDLOCK concept and its combination of a mechanical lock with magnetism come into play: The magnetic attraction guides the fastening components into the right position, where they are secured in a mechanical lock. Magnetic fasteners by FIDLOCK are opened by sliding laterally, pulling or pushing which purposely differs from the closing process. This causes “reversed polarities” of the magnets, allowing easy, single-handed operation of our buckles or fasteners.

As you can see, magnets are indispensable for the innovative characteristics of the FIDLOCK concept. However, not any magnets would suffice the quality standards of FIDLOCK magnetic fasteners or buckles. A strong attraction is central for high-quality magnetic fasteners and neodymium magnets’ reputation as the strongest permanent magnets precedes them. Their magnetic force is very high, even when they are only a few millimetres big. Therefore, they are ideal for the use in small components, keeping the fasteners small and light and allowing inconspicuous application possibilities.

Magnetic strength alone doesn’t make a good fastener

Of course, more reasons justify neodymium magnets as the ideal choice for FIDLOCK’s purposes. Buckles and fasteners need to be durable, keeping in mind that applications like bags or shoes are opened multiple times a day! Naturally, one question keeps popping up: How long will the magnetic force last? People need to rely on the properties of FIDLOCK fasteners in many situations. Neodymium magnets have a very high coercive field strength. In normal language: They are highly resistant against demagnetisation through other magnetic forces. This keeps the attraction of our fastening components upright – even with constantly reoccurring interference through magnetic fields from laptops, headsets and many other devices.

Strong neodymium magnets in fasteners – not interfered with, but affecting?

There are some questions people repeatedly ask, regarding the effects of magnetic force fields coming from neodymium magnets. Can I transport my credit card in a bag with a magnetic fastener? Isn’t a magnetic buckle on the strap of my camera bag dangerous for my saved images? These questions can be answered easily:

Magnetic forces weaken rapidly as the distance from the source is increased. Even maintaining small distances, we already keep by habit, avoid erasure problems. For example, credit cards are interfered with when a magnetic force of 30 mTesla is reached. 0.1 – 0.3 cm distance is enough to keep headsets with 32mTesla (measured in our example) from influencing magnetic strip cards. However, FIDLOCK is uniquely innovative by insulating the magnets within the mechanism, already achieving far less magnetic force in their direct vicinity as compared to bare magnets. The FIDLOCK MINI TURN is sealed to the inside of the bag which makes putting a credit card in the bag unproblematic. Additionally, the closed SLIDER with protective shield offers similar security.

Many people fear possible effects of magnetic fields on electronic devices, such as cameras, smartphones or even USB sticks. This fear can be taken. Modern electronic devices use flash memory, operating with electronic force fields, which leaves them unaffected by magnetic force fields. Older devices that use a hard disk storage unit (e.g. iPods from 2004 and earlier) could be influenced by magnets if they get too close. As aforementioned, FIDLOCK fasteners and buckles already have an embedded or recessed magnet within the mechanism that already generates a distance to the magnet, virtually reaching the minimum security-distance.

Regarding components with neodymium magnets or rather magnets in general, caution is always advised with pacemakers, defibrillators or other devices with so-called reed-switches. These switches are operated through magnetic force. This, for example, allows a doctor to influence the patient’s device without surgery. Generally, patients with pacemakers are introduced to the correct distances and possibilities concerning magnets. As a rule of thumb, a distance between 20cm and 30cm to unobstructed magnets is advised. However, it is always recommended to follow the instructions of the pacemaker (or similar devices) and ask a doctor or the manufacturer of the pacemaker regarding uncertainties.

That was enough theoretical talk for now. This clarified that neodymium magnets are essential for the ease of use and fun connected to the moment of opening or closing a FIDLOCK magnetic fastener – why not see for yourself?
