This can be measured using the energy density, which is given in kilojoules per cubic meter (kJ/m³). Some hold six hundred times their own weight. We also refer to neodymium magnets as super magnets because their adhesive force is much stronger than that of ordinary ferrite magnets. Why are neodymium magnets called super magnets? Hard drives run faster, speakers perform better, it all works because of a small magnet with superpowers. Branches of industry such as PC and mobile phone manufacturers, engine workshops and high technologies are now unthinkable without neodymium magnets. In this respect, neodymium magnets are not only ultra-strong, but can also be used at full power under extreme conditions - such as high temperatures in industrial plants. Scientists assume that both the magnetic force and the hot spot can even be significantly improved soon. New technologies ensure that the heat point at which neodymium magnets lose their magnetism has already shifted far upwards. Industry and hobbyists rely on an effective force that is many times greater than that of ordinary magnets - for example compared to ferrite magnets. Tip: Self-adhesive magnets are extremely versatile, as they stick practically anywhere. Before you buy neodymium magnets, you should think about the shape that is ideal for you. But they are among the strongest magnets in the world - and this is already the case with small models of just a few centimeters. Accordingly, neodymium magnets are quite expensive compared to other magnets. The special and difficult thing about these metals is not their rarity, but the complicated extraction and release from other compounds. Neodymium is one of the so-called "rare earths". Neodymium magnets are also commercially available under the designation neodymium-iron-boron or NdFeB magnets. Strong neodymium magnets (NdFeB) – The super magnets
