New Alloy Becomes Magnetic on Heating

This video is short, and really pretty boring if you don’t know what’s going on. Shown is a chunk of new alloy that undergoes a phase change, at about 125C, from a nonmagnetic material to one that is strongly magnetic. If you bias the system with an additional, permanent magnet, heating the system past the transition temperature produces an electric current in a nearby coil, thereby converting heat to electricity.
