For years, researchers have pursued a strange phenomenon: When you hit an ultra-thin magnet with a laser, it abruptly de-magnetizes. Imagine the magnet on your refrigerator suddenly falling off.
Now, scientists at CU Boulder are digging into how magnets recover from that change, regaining their properties in a fraction of a second.
According to a study published this week in Nature Communications, zapped magnets actually behave like fluids. Their magnetic properties begin to form “droplets,” similar to what happens when you shake up a jar of oil and water.
