After all, Nar’s Gold cannot be useless



(Newser)
– Pyrite looks like gold but historically none of the value – hence the nickname stupid gold. But scientists have now come up with a way to make the common mineral much more appealing – and during the process, they electrically induced magnetism in a non-magnetic material for the first time per new Atlas. Few materials exhibit the strongest form of magnetism, known as ferromagnetism. But researchers at the University of Minnesota turned non-magnetic pyrite, also known as iron sulfide, into such a material. They first put pyrite in contact with an electrolytic solution similar to Gatorade, according to Fox News. They then applied one volt of electricity ̵

1; less voltage than one household battery per release.

It was enough to move positively charged molecules to the connecting areas and create a magnetic force. “By applying the voltage, we essentially pour electrons into the material,” explains lead researcher Chris Leighton. “It turns out that if you get high enough concentrations of electrons, the material spontaneously wants to become ferromagnetic.” When the tension disappeared, so did the force, according to the study published on Wednesday Scientific progress. In other words, magnetism can be turned on and off. “This has a lot of potential,” especially for more energy-efficient computer memory devices, which would otherwise require ferromagnetic materials such as iron, cobalt and nickel, says Leighton. “After doing it with ferrous sulfide, we assume we can do it with other materials as well.” (Read more discovery stories.)
