Hidden inside are tiny magnets made from rare earth elements: obscure minerals that help power everything from smartphones and wind turbines to fighter jets and electric cars. They're also at the centre of one of the biggest geopolitical struggles of our time.

In this episode, Ed Conway follows the story of rare earths from an obscure Swedish town and the Manhattan Project to modern China, where decades of industrial strategy have given Beijing extraordinary control over a resource the rest of the world depends on.

Along the way, he explores the strange economics of rare earth mining, the environmental costs hidden behind modern technology, and the growing fear that global supply chains can be turned into weapons.
