Compact and strong rod magnet of neodymium in high grade of magnetisation (N48), an elegant pin board magnet, easy to grasp. Also suitable to create impressive compact Platonic solids. Neodymium magnets are made of neodymium, iron and boron and are the strongest raw magnets.
Warning: Not suitable for children under three years due to small parts. Magnets are no toys. Inappropriate use might cause injuries.
As the world invents and develops, we humans are continuously being introduced to new materials and methods for improving our living standards and making life easy. Leaps in the magnets industry is yet another area of development and focus. Neodymium is basically a rare Earth element which is mixed up with other important elements such as iron and boron to produce the world’s strongest permanent magnets. These permanent magnets are infamously known as neodymium magnets as well as neo, NIB, NdFeb and super magnets commonly. The extreme strength threshold of these magnets can be understood from the fact that even a small mass has the ability to easily support a load a thousand times its own weight. Due to the easily available raw materials along with the affordable price and remarkable product performance, neodymium magnets of all shapes and sizes are mass produced and are readily available for numerous applications in electronics, jewelry, toys and various industrial equipment.
Neo magnets come in various grades from the weakest N33 up to the strongest i.e. N55 in terms of magnetism measurement. More commonly, the quality of the magnet purchased is also dependent upon the place or company of purchase. NIB production is carried out through separating neodymium from other minerals through sifting and then combining it with other elements such as boron and iron. Certain problem posing characteristics of neodymiums are fragility and brittle in nature which may result in instant chipping or breakage in cases of high momentum collisions. However, such magnets are more usually covered with a strong protective coating in order to prevent rusting in response to the presence of iron in them. In addition, if these super magnets are heated to temperatures above their Curie value that would result in instant, permanent and irreversible demagnetization. sintering ndfeb rod magnet
