Part 8/14:
Throughout the discussion, the hosts emphasize that what is often presented as "real magnetic fields" are, in reality, projections or illusions—visualizations of the underlying fields from specific vantage points or with specific sensor orientations.
They compare this to the difference between looking at a shadow (projection) versus the actual object. The maps, orbital shapes, and field lines are often just projections, misleading those unfamiliar with the core physics.
They argue that true magnetic monopoles—single magnetic charges—do not exist in nature, and what is often called a "magnetic field" is actually a multi-pole phenomenon, made clear through the use of spherical harmonics and complex mathematical models.
