Pros and cons of using neodymium magnets

Alexandria, Virginia-Neodymium. Its name already sounds exciting. this is new. It is dynamic. It forms the alloy Nd2Fe14B with iron and boron, which is probably the most powerful permanent magnet on earth. The strength of neodymium magnets can be reminiscent of the scene of ants taking away the entire sandwich; even a small neodymium magnet can lift a thousand times its own weight. Nd2Fe14B magnets can achieve some impressive feats, but operators should still be aware of some shortcomings when deploying these powerful magnets-these shortcomings, if not properly cared for, can endanger the life of the magnet. When using neodymium magnets, please keep in mind the pros and cons of using neodymium magnets.

Let's start with the basics. Neodymium magnets have the best power-to-weight ratio of any magnet. If you need raw power, then you can't do better than this. This magnet is not only incredibly strong; it is also very good at maintaining this power. With proper handling and moderate temperature, your neodymium magnet will continue to serve you as long as you avoid getting wet.

The Wicked Witch of the West, Gremlins and neodymium magnets: three things you never want to get wet. Everyone is familiar with the sensitivity of iron to corrosion, because iron is present in neodymium magnets—14 atoms per molecule, 2 of the element neodymium—you will find that they are as susceptible to moisture damage as traditional iron magnets. If not, even more so. Do not use neodymium magnets when they may get wet, and do not store them in areas that may contain too much moisture. In these applications, you may need to consider different lifting magnets.

Speaking of lifting capacity, how can it be possible to get the best without spending the most money? Just as the strength of a neodymium magnet seems to ignore its size, so does its price. Nd2Fe14B is generally a more affordable alternative than competitors, making it ideal for many industrial applications.

Among the pros and cons of using neodymium magnets, perhaps the reader is most surprised how such a powerful thing is so fragile. Indeed, you don’t want to accidentally swing in these magnets and let them collide with concrete, metal, or any hard surface. The neodymium magnet does not need a high psi to break. Debris, cracks, and complete fractures can severely affect the magnetic integrity of the unit. Avoid careless handling that can damage your neodymium magnet.

Nowadays, neodymium is not cheap, and dysprosium, which is often used with Nd, is at a disadvantage in terms of supply.
