named pillars wish to find the nation. and to nadia, these gatherings are way to help that homeland too. and you're up to date, splendid. 8 is up next looking at how a little known. but a central super magnet came close to setting off a damaging trade war will be back with more at the top of the next hour by the come have a pages this out to the highlights you every week in your inbox, subscribe now. so you don't think and feel the same way you expect and want different things from life and your parents. i just want to pursue what that's nice on fire or you think your kid is 2 different, risky, irresponsible, unreasonable,

all stuff. and i want my son to become a doctor to in the clouds. it's time to us and then when generations class this week on dw, the. ringback on september 7th, 2010 seemingly small incident in the middle of the eastern us change the course of history. chinese preaching trauma and to japanese coast guard ships collided in the disputed waters. the japanese coast guard detained this coupon. tensions between the 2 countries had been rising. o. yeah. and the chinese government was it canceled high level political meetings with japanese officials, reportedly reduce exports of crucial re of elements to japan. china has denied this has happened and is paid by how much they reduce their exports. but what is clear

is that the small events mock, the stock of an incredible price search in a world wide frenzy to secure these rare elements, arguably the most. and of them being this new to me as a weird little element that will tell, i'll shoot you, the new domain is hidden all the way down here in the pediatric system. it's one of the 17 read us elements which are actually not that rare at all. these metals were 1st considered rad because they have never been seen before, but really like new to me and quite abundant in the us crust. it's just very hard to separate them from the material around them. what it was discovered in 1885 by this austrian scientist. nobody really knew what to do with it. from the 19 twenty's onward, it was used to color the last type of fancy, but still not very useful. but in 1983 researches from general motors and the japanese conglomerate. so me to more independently announced

a huge invention at the same conference. if you combine new demi em together with boy on an iron, you'd get really, really strong magnet today. now gimme a minute, self is also used in special protective last, and felicia is among other things. but the magnet is what turned out to be a game changer. this is a regular affair, right? magna probably what's in your normal fridge magnets? i mean, they're super easy to separate. no problem. this is what's called a supervisor. and they are super strong. oh my god, the, i swear to god, i'm not that week. now do me a magnus can be up to 10 times stronger than fair, right? magnets normally, the 9th is ation of breaks up into the different domains punching in different directions. this is michael kelly, a professor who has been researching magnets for over 50 years. we don't want that

to happen to have a good use use of a permanent magnus. we want them all to be in the same direction. and the way you do that is allowing the, with another element, which is new to me, which is the best one. for this purpose, that makes me now give me a magnets crucial for things like electric cars, wind turbines, or even your phone. so a quick refresher why we need magnets for these things in the 1st place to are making the simplest electric marta from these monuments a battery and some copper wire frustrates for this battery on couple of these magnet. so and then you need to form your copper in a type of full service. now the me a magnet or the creating a really strong magnetic field. this battery is low energy, so the top of the list, couple subordinates to touch the battery. and the bottom pop needs to touch the

magnet so that the electricity can flow through the and this happens because of a principle called the lawrence for you may remember from high school, this is how we convert electrical energy into mechanical energy. so this is a basic principle of how an electric model to works, and that's what we use also for electric cos, the same principle, good for wind turbine. just the other way around. this mechanical energy is then turned into electrical energy through the magnet inside here, and the call us boil. so in the bigger versions of these, instead of the l, a. d being looked up, that's the electric energy that the generated. it's fed into the grid. so the strong of a magnet, the better and leave now do me a magnets of the strongest commercial magnets on the market. they also relatively

cheap, and see the how to de magnetize the invention of now, do me a magnets paved the way for more efficient electric motor. the moon come back and the light to because these magnets are so powerful that even comparatively small ones get the job done. today, many electric cars contain an average of about the kilogram of new do me a magnets. wind turbines use much, much more up to posit tongue turbine. these limits are also really important in order to equipment like these headphones, old big speakers inside these broken headphones. this still should be something magnets. so list to get. well, that was easy in these headphones, you have a cup of spoil and a magnet. the electricity is converted into movement, which then is converted into audio waves. in the case of your phone, there's a tiny magnet in here, and that causes the sun to vibrate. most of the new domain,

well, life is going to be use for electric, causing wind turbines without popping up everywhere. this is why the mountaineer do me and it's only projected to grow and could out strip supply. but let's rewind back to that boat incident for a minute. it wasn't just depends that kind of good little when they realize how dependent they have become on, read us mind and china. the price of me or do me, i'm showing up dramatically after the collision. it's all born out of this, this fear from the big, the concentration that you the race and it's been 20 times with china. this is michelle bustamante. she looks like critical minerals and their impact on land and natural resources. i have seen that concerns around these types of materials lead a lot of countries to become more resourceful, naturalist and i solution s and want to mine all of our own stuff and only,

you know, produce everything domestically draining. yeah, we read us relatively abundant, has scaled up its production significantly. the us reopened. it's one rate of mine in 2017. yamaha has scaled up it's mining, but exports. a lot of it's rare us to china. india wants to quit drupal, it's domestic production in the coming decade. but scaling up near do me and production is still far from easy. the problem is getting this elements out of the new do, ma'am, is found jumbled together with other similar elements purifying. it takes a lot of steps that process use as many acids and sold instead of detrimental to the environment and hazardous to work as not only that, whenever unique challenges associated with rear or mining often is that they're mixed up a lot of the or is mixed stuff with highly radioactive elements. that's why even 10

years after the f crisis, china is still the main producer of these elements. and they would do me along with other writ of elements has been pop tockets during recent trade. tensions and prices are starting to search again. the problem is that these new domain magnets so great that it's really hard to replace them. but people have tried to find other ones, other combinations of on with different rats. and some of them have been somewhat successful, but nothing as good as meeting them. all these details about the metallic g. much, much to what does the work though, is using less of it more efficiently? for example, in electric motors, we found that b s, you could actually replace 50 percent off from your day me. i'm with fairway marketing without compromising performance. this is a can on livid in cheese, a chemist, developing new methods to recycle and substitute new dom your magnet the so

is it mother of all penalties and substitution, but not for the entire replacement. recycling always seems like the most obvious solutions, but when the very early stages still in personal electronics, these magnets are small and hot to retrieve because they're built in with other materials, making it easier to just use new new to me. but since the wind turbine and the electric call markets are also expected to keep on growing, it could incentivize more recycling. and since the magnets use there a bigger it could be more cost effective. i can tell you that we are making version for risk approach is to recover these rarest elements in an environmentally friendly way. using that process, we call the assets free, the solution office. with this method, there is no need to pre sold and separate out rid of magnets, one by one instead of toxic assets. the process use is called the sold and selectively lead to our red us. and these are examples of forever elements that

we're recover from the it would make it even easier if manufacturer is already built. they've products with recycling in mind when we create the currently sustainable supply chains that involve a high degree of reduce recycling. that's when we're really gonna solve the problem is that create all this fear not just by trying to mind everything ourselves as individual nation. so it's unlikely that this obscure element is going out of fashion anytime soon. did you know about super magnets in there? do me m, please let us know in the comments and subscribe. read those videos like this. every 5 the,
