Rare earth magnets, like that of Neodymium-iron-boron, are used in sensors, and even ferrite magnets contain small amounts of rare earths and minor metals like Lanthanum and Cobalt to improve magnet performance by as much as 25%. GPS navigation, touch screens, power windows, and all the hi...
The article looks at the governmental restrictions, mining efforts, and the possible alternatives to rare earth metals (REMs) in China and the U.S. According to International Union of Pure and Applied Chemistry (IUPAC), they are also called rare earth elements and consist of 15 elements such ...
The U.S. used to be a top manufacturer of rare earth metals back in the 1960s, but eight years ago environmental infractions shut down the Mountain Pass, California mine, the largest deposit of rare earth metals outside of China. Currently, there are efforts to restart production at the ...
we also take for granted a group of elements called rare earth metals, whose special electronic and magnetic properties make them a key component of many 21st century technologies. These 17 elements are actually plentiful

Rare earth elements Sources: China, U.S., and Australia27 Found in: Electric motors in all EVs. They are found in some batteries and electronic components of other vehicle types. The importance of rare earth metals in the automotive industry, particularly for electric and hybrid vehicles, lies...
Are there metals far scarcer than iridium and enormously more expensive than gold — while at the same time, non-radioactive or very, very nearly so? As it happens, yes. A line of radioactive cosmetics introduced in 1930 Each element comes in varieties called isotopes whose atoms differ in...
Other metals besides iron can have ferromagnetic properties. These include nickel, cobalt, and some rare earth metals such as samarium or neodymium, which are used to make super-strong permanent magnets. Other forms of magnetism Magnetism takes many other forms, but except for ferromagnetism, they...
the welfare of humanity, as it allows people to predict and prepare for natural disasters such as hurricanes and volcanic eruptions. It also helps people locate and extract valuable raw materials that are hidden underground, ranging from fresh water and fossil fuels to minerals and precious metals...
