Super Magnets: All About Rare Earth Metals [infographic]

A few years ago my brother got me Buckyballs from woot; a few years later I finally put them down. These things are the most addicting toy your adult self will ever experience.

Sometimes you’ll use them to pin the electricity bill on the fridge. Sometimes you’ll spend two hours trying to get them all connected in the shape of a diamond. Why would you spend two hours putting them in the shape of a diamond? Well, I don’t know, but I’ve done it multiple times.

Playing with these magnets make you feel like a magician. They are strong enough to magnetize through your hand, desks, sometimes even walls. I know a middle school teacher who has a massive collection of these – confiscated from her unfortunate pre-teens. Its safe to say she never gets bored at work when she can spend some time with these rare earth metals.

When I was in fifth grade I had a project where I was assigned an element from the periodic table: neodymium. I’ve never thought I’d have this element in my own hands, yet Buckyballs are completely built with the greatest substance known to me. Now, I don’t hand out my personal endorsement too often, but these things will make your days. [Buckyballs]

    A little homework shows the staggering environmental impact of “green” technology. The drinking water in some parts of Baotou is so toxic you can’t even irrigate farmland (villagers drink it anyway). Cancer is on the rise, health is poor for many, teeth falling out at a young age. Sad really.

    You write “10’000’000 tons, more than double the capacity of Michigan lake”. 10’000’000 tons is 1*10^7 tons. Lake Michigan has a volume of 4920 cubic km of water, that’s 4.92 *  10^12 tons, roughly 500’000 times more than the 10 Mio tons mentioned.  Your comparison is therefore off by a factor of 1 million. (1 cubic km = 1000 x 1000 x 1000 m3 = 1*10^9 m3).

    A neodymium magnet (also known as NdFeB, NIB, or Neo magnet), the most widely-used type of rare-earth magnet, is a permanent magnet made from an alloy of neodymium, iron, and boron to form the Nd2Fe14B tetragonal crystalline structure.
