Here's a fun, customisable fridge magnet for your pet!
On a slightly more serious note, all sorts of gadgets and devices are powered these days using magnets made from rare earth metals. These metals are being utilised increasingly in very high-tech systems and their success brings a boost to the economy. Rare earth magnets are made from the elements neodymium, iron and boron and so are known as NdFeB magnets. NdFeB magnets are the strongest magnets you can get (except for superconducting magnets). Rare earth metals are now utilised to improve the efficiency and performance of numerous technologies, including the magnetic technologies that power hybrid and electric vehicles, aircraft controls, loudspeakers, mobile phones, wind turbines, loudspeakers, factory automation equipment and robots! Rare earth metals have enabled the miniaturisation of all of these systems, making smaller, more compact components. |
