The forum discussion centers on the nature of magnetic field lines, emphasizing their representation in two-dimensional sketches versus three-dimensional models. Participants, including Greg Bernhardt and Ibix, highlight that field lines should ideally be depicted in 3D to accurately reflect the inverse square law of magnetic fields. The conversation also touches on the complexities of visualizing these lines, particularly in relation to moving charges and the limitations of using iron filings for demonstration. Additionally, the discussion mentions the need for animations or stereograms to better illustrate these concepts.

As a beginner I am not aware of EM formula without the concept of fields. I will learn it. Thank you for your advise.bhobba said:That EM can be formulated without the concept of field shows convenience is often used to decide how to view something.
