The power of magnetic waves is evident to any Boy Scout with a compass. A Dutch firm is applying amplified magnetic force to the task of peeling an onion.
Rare earth isn’t just a rock band; it’s also a group of 17 chemical elements, some with notable magnetic properties critical for permanent magnet alloys for cordless tool motors and computer hard drives. A group of Dutch engineers recently harnessed the power of rare earth magnets to manipulate the motion of onions as they are peeled, replacing mechanical motion with the frictionless force of permanent super magnets.
