Maybe we heard it as a child in school or as we got older within our business circle Previously, old magnets could not be recycled to reuse the rare earth metals inside them, but new methods hav Jobmaster Magnets Canada Inc.

They Get Old While the passage of time does weaken the strength of a magnet, the changes are very slow. Reluctance Changes When the operating slope of a magnet is modified, the variance can cause a shift in magnetic charge.
External Charges Magnets that are not protected from outside magnetic fields may fall prey to loss of magnetic charge. Like This:. What Does Ferrous Mean? And what is Non-Ferrous? Our vast inventory of more than a million magnets, makes us a leading magnet supplier in the industry. So how do you remagnetize a magnet, and win back the power? How do you remagnetize a magnet? You remagnetize a magnet by bringing it into contact with a strong magnet. So, if you have a weakened magnet, you must carefully bring it to contact with a strong neodymium magnet.
This will make your weakened magnet regain its magnetic force. That was it. The short and simple answer on how to remagnetize a magnet. During the next sections, I will elaborate on how you safely and effectively remagnetize a magnet. This can happen because of several reasons, which I will explain later.
If you want the best possible result of the remagnetizing, you need to take you a weakened magnet and touch one of its pole with the opposite pole of a strong neodymium magnet. It is important that you use a magnet where the two poles are clearly indicated.
You should also be careful using very powerful neodymium magnets for this matter. Even though the strongest neodymium magnets are very important for many modern applications in industry, manufacturing, science, and production, they can simply be too strong to handle. If you want to make sure that you use a magnet that is safe to use for this application, please choose one of our recommendations below.
Now, back to how you remagnetize a magnet. As I mentioned before, you must point your weakened magnet towards the opposite pole of a neodymium magnet.
Once you have obtained a neodymium magnet, you must find out which end of the magnet is the north pole and which is the south pole. The best way to do this I used a compass. If you bring a compass near neodymium magnets north pole, the needle will point towards the south. If you can find a very strong magnet, repeatedly rub it across your weakened magnet. The strong magnet will realign the magnetic domains inside the weakened magnet [source: Luminaltech].
Magnet stacking One way to make weak magnets stronger is by stacking more of them together. There's a big problem with this, though.
Magnets attract each other in opposite directions, which will lower their overall strength. If you can find a way to hold or clamp them together, so they're aligned in the same direction, they will in fact produce a stronger magnetic field [source: Balbach ]. Magnet FAQs What materials would make the strongest magnet? The strongest magnets are made from an alloy of iron, boron, and neodymium. How do magnets work? Magnets have north and south poles that are attracted to each other. When an object is attracted to a magnet, it causes the the north-seeking poles of the atoms in the object to line up in the same direction.
A magnetic field is created by the force generated by the aligned atoms. Thus, the object and the magnet bond. How do you make a stronger magnet? Place your weak magnet next to a much stronger magnet.
