Rare earth magnets refer to a special type of permanent magnets that are made from alloys of certain rare earth metals. These varieties of magnets were made during the 1970s and the 1980s and are commonly used to produce stronger fields.

Magnets themselves are not rare and they are made of metal which is not uncommon either. In fact, the magnets, as well as the metals, are quite commonly available. There are two popular varieties of rare earth magnets and they are neodymium and samarium-cobalt magnets.
What Samarium-Cobalt Magnet?
This variety of magnet first manufactured in the early 1970s. Magnets are usually manufactured with a special reduction / melting or methods of reduction/diffusion in which the raw material melted in an induction furnace with argon gas.
The mixture is melted and then cooled player to make ingots. ingot crushed to create particles that are then pressed into molds to make magnets. Although this magnet is relatively easy to make they are not very popular. The manufacturing process is expensive and time-consuming.
What Neodymium Magnet?
This wide range of Magnets invested in the late 1980s and they quickly became popular. Now the most commonly used variety of rare earth alloys and consist of neodymium, iron, and boron.
This variety is also produced in the same manner by sintering or by the rapid freezing but produces a very strong metal that is now used in various applications.
