Part 3/9:
A particularly interesting observation was how the magnet interacted with large copper plates—each approximately three feet long and a quarter-inch thick—placed side by side. When they rolled the magnet along these plates, they noticed a pronounced resistance depending on the magnet’s orientation. If they positioned the magnet with its south pole facing outward and rolled it, it behaved differently than when oriented differently. For instance, when aligned so that the poles or magnetic fields are facing a certain way, the magnet would either tumble or slide smoothly along the metal surfaces.
