From computer hard discs to smart phones, magnets are at the forefront of technology. Magnets containing rare-earth elements are among the most powerful available, but these elements can be difficult to obtain. Now, scientists have identified magnets based on more readily obtainable rare earths, as well as some promising magnets that don't contain these materials at all.
