Disc magnets are very strong made through a production process that involves creating alloys from natural elements. Typically, the elements are rare earth metals, also known as rare earth elements and neodymium, in many cases. The neodymium magnet is the most powerful. Disc magnets have a large choice of uses in science, technology, and regular life that can be applied for many functions.

Rare earth metals are called this term because they belong to a class within the periodic table of the elements known as "rare". Yet, these 'rare' earth metals are very easy to find because they are remnants of mining minerals. Ceramic magnets are another kind of it that is created by mixing ceramic, alnico, and iron. Even so, ceramic magnets are less magnetic than rare earth and are not used often by manufacturers commercially.

Even though the neodymium is only one millimeter in diameter, this kind applies enough force to remove all of the information from a hard disk drive. However, these are fragile so two will disintegrate if they were to collide, which would send shards flying out and cause injury. Also, you can hurt your fingers by using it if an individual who holds the two magnets cannot hold onto one. They are made by the reputable General Motors Corporation and contains a combination of neodymium with boron and iron.

Neodymium magnets are increasing in use because of the increasing trend for manufacturers to want to create stronger and more powerful hard drivers and speakers. The manufacturers also make very small magnets to go into small electronic parts. For instance, some hard drives have a small neodymium magnet within a thin plate. The strength of it in comparison to the alnico magnets is unsurpassed. An alnico magnet has to be at least ten times larger than a neodymium magnet in order to use an equivalent force within a hard drive. This is proof that these magnets are much bigger than their alnico equivalents. Additionally, disc magnets are a good way to store items or to hold them up or keep them apart is to use a disc magnet. The magnets are made in the shape of a disc and can be found anywhere. People use them to keep binders and portfolios shut and also as bulletin board tacks. They are also used to hold papers on a fridge, to straighten and secure a cabinet door, and more.

Recently, the commercial use of disc magnets has expanded. Neodymium disc magnets have been made to replace specific magnets like ferrite magnets and alnico. The neodymium magnet is very small but very strong. With a good understanding of a magnet's strong and weak points, disc magnets are a good tool that keeps items together, keeps them out of contact, and stores items.
