  • Creation of a Completely Rare-Earth Free Feni Magnet is Now a Possibility

The creation of a rare-earth free Feni magnet is now a possibility. Science sure seems to have progressed beyond our wildest dreams.

This is a first and it has made scientists proud of their field of endeavor beyond belief. The relatively inexpensive production of a rare-earth free Feni magnet has become a reality. It was via the use of the simplest industrial technology imaginable.

The experts at a Japanese university have created the material virtually from scratch. With support from MEXT the project got completed and it was quite an achievement. The magnet that got made was an improvement over meteoric magnet that was formed over the course of billions of years. This one got made on earth in a matter of a week and a half. 

The magnets of the future will be quite different than the current ones thanks to this discovery. The quality magnets found today are employed in vehicles, household eletronic items and medical paraphernalia.

They are made of rare-earth elements. These include samarium, neodymium and dysprosium. The provenance of this sort of magnet is Japan. The keeping up of production of these magnets is becoming a difficult proposal. 

The issue is actually political and economic in its nature. Worldwide production of such magnets requires that they be formed free of rare earth elements. This is not only so in Japan but throughout the rest of the global village. The fact that necessity is the mother of invention holds true here. The 60s was a time when it was proved that Feni magnets were a part of the natural meteorites that were extant in the universe billions of years ago. The production of these magnets in an artificial form had been extremely difficult so far. But such is not the case anymore. 

The research team at the Japanese university finally reached its objective via high atomic diffusivity at very cold temperatures. The crystallization that takes place from a blob-like shape is where the magnetic properties arise.

The whole process is almost like going in a time machine back in time and changing some of the conditions way back when the magnetic rocks formed in the core of the meteorites.

Thus you can see that thanks to the miracles of science, the formation of the natural magnet can be copied in an artificial environment without any difference being visible between the two processes at all.
