Revealing the thermal heat dance of magnetic domains

Everyone knows that holding two magnets together will lead to one of two results: they stick together, or they push each other apart. From this perspective, magnetism seems simple, but scientists have struggled for decades to really understand how magnetism behaves on the smallest scales. On the near-atomic level, magnetism is made of many ever-shifting kingdoms — called magnetic domains — that create the magnetic properties of the material. While scientists know these domains exist, they are still looking for the reasons behind this behavior.
