Part 4/8:
Paul then explores how magnets with same poles glued together versus those with opposite poles attracting behave. On a CRT screen, he captures the magnetic field patterns:
When like poles are joined, the field appears more condensed and protrudes outward more prominently.
Conversely, opposite poles attract, and the field lines spread apart, indicating different internal arrangements of magnetic flux.
He also notes an unusual visual artifact—a black shadow bar across the screen—that appears only in the camera feed, not to the naked eye. This mysterious shadow suggests the complexity and perhaps some unseen dynamic in magnetic fields that merit further investigation.
