Part 3/6:
The participants hypothesize that the magnetic stainless elements within the tester have migrated towards the center, giving it unique properties. Don demonstrates an effort to reposition the tester to see if it would respond to the opposite pole. However, the magnet remains uncooperative, leading to speculation about it acting similarly to a magnetic monopole—investigating this behavior sparks memories of previous experiments involving a file of metal that had similar magnetic characteristics.
