Ever wondered what’s so special about speakers and headphones which proudly exhbit the fact that they have Neodymium? Well, I certainly have. First of all, what is Neodymium? It is a rare earth metal which is used for a variety of purposes like making magnets. That explains its presence in speakers & headphones. It turns out that Neodymium is used to make some of the strongest magnets. Also, looks like we have our share of Neodymium in computers too – its used in the hard drive head motors.
