Raw magnets made of neodymium (NdFeB) - the super magnets
Raw magnets made of neodymium - real super magnets!
Neodymium magnets are also sold under the name neodymium-iron-boron or NdFeB magnets. Neodymium belongs to the rare earths. The problem with these metals is not their rarity per se, but the difficult extraction and release from other compounds.
Accordingly, neodymium magnets are not the cheapest magnets, but they are unbeatable among the strongest in the world, even in small sizes of a few centimeters. So all you have to do is decide which shape you need. We carry disc magnets, cone magnets, ring magnets, bar magnets, block magnets, cube magnets and spherical magnets. Self-adhesive magnets are extremely versatile, as they stick practically anywhere.
Super magnets for hobby and industry
Industry and hobbyists rely on an effective force that is many times greater than that of ordinary magnets. Nowadays, new technologies ensure that the heat point at which neodymium magnets lose their magnetism has been set way up, and scientists assume that this, as well as the magnetic force, can be significantly improved in the near future. In this respect, neodymium magnets are not only extremely powerful in terms of performance, but can also be used at full power in extreme areas. Industries such as PC and cell phone manufacturers, engine workshops and high technologies are now inconceivable without neodymium magnets. Hard drives run faster, loudspeakers perform better, all because of a small magnet with superpowers.
Handle with care
Such strong magnets naturally also inspire private individuals. However, there are a few principles to be observed.
What should you watch out for when handling neodymium magnets?
Neodymium magnets should not be near people with pacemakers, and children should be kept away from magnets. Neodymium magnets should not get near fire, welding and soldering are also taboo.
Otherwise you can do handicrafts with neodymium magnets or organize nice gadgets. Find your key ring with a bar magnet or place cube magnets, block magnets or spherical magnets in different sizes as decorations on a shelf. You can use it to collect metal shavings or sewing needles, or take a walk to test everything that gets stuck to your disc magnets.
Self-adhesive magnets stick to almost all surfaces. You peel off the protective film, stick this part on and the remaining magnet parts stick to each other while the permanent magnet is firmly in place. You may be familiar with ring magnets from medical practices specializing in alternative medicine. Otherwise, the different widths, heights and diameters are suitable for many possible applications.
How stable is the adhesive force of neodymium magnets?
With normal treatment, neodymium magnets do not lose their adhesive force. However, direct contact with strong magnets and high temperatures can lead to demagnetization.
At what temperatures do neodymium magnets demagnetize?
That depends on the magnetization quality. With the most common grade N45, the maximum temperature is approx. 80 ° C. If the magnet becomes warmer, the magnetic properties are lost.
Robust beauties for many areas of application
The nice thing about neodymium magnets with zinc, nickel or copper coating is their weather resistance. The simple metallic beauty is not only a pleasure for figures made of spherical magnets. Perhaps you also use cone magnets and disc magnets for magic, they are an unbeatable tool. In addition, neodymium magnets are wonderful, unusual gifts.
