Lifespan of a magnet

At Magnetpartner, we have chosen to focus on permanent magnets – that is, magnets that are magnetic without the need for electricity or technology. And it makes perfect sense to call them "permanent" magnets, as they have a long lifespan. Find out more about them in this post. You can also explore other topics on magnetism if you are more curious about them.

Strength and endurance that lasts for decades.

It's amazing how long magnets can hold their strength. Research and experience have shown that magnets, like the ones we sell here at Magnetpartner, retain their optimal strength for at least 80 years, according to research and experience. This means that, despite decades of use, the magnets will still be as powerful as they were on the day they were maufactured.

What is even more interesting is that it takes close to 100 years before one begins to notice a decline in strength without the use of specialized instruments. The gradual decrease in strength in magnets can be measured after about 80 years, but it takes close to 100 years before we can feel it ourselves when comparing two identical magnets. This exceptionally long period of unchanged performance makes magnets an exceptionally reliable and durable solution.

Advantages in technical and industrial contexts

The strength of magnets offers significant advantages, especially when used in technical and industrial contexts.
Constant strength ensures reliability in applications where precision and consistency are critical. The nearly imperceptible demagnetization over time ensures that magnets can maintain their performance for decades without needing frequent replacement. After 80 years, the magnets will lose a bit of strength, so if you plan to use them longer than that, you should choose a magnet with a higher strength than initially required. But on the other hand, it's easier to replace the magnets after 80 years than it is to constantly replace other parts that aren't as durable as them. The combination of metal, neodymium, and a design that shields the magnets from impacts makes for a truly robust solution that will last for generations.

Magnets as a sustainable solution

The ability of magnets to retain their strength over an extended period is not just a technological achievement but also a significant eco-friendly characteristic. Their longevity and minimal degradation make magnets a sustainable investment that benefits not only users today but also future generations as mentioned above. Consider integrating magnets into your next project and remember, a magnet used today to assemble a piece of furniture or build a small motor might in the future serve as a strong whiteboard magnet if the furniture or motor ceases to exist. Thus, magnets are an excellent solution for green investments.
