Is the Configuration of Magnetic Fields Only a Convention?

Click For Summary
The discussion centers on whether the configuration of magnetic fields is merely a convention, similar to the historical choices made regarding positive and negative charges. It explores how Faraday and Ampere's differing perspectives on magnetism influenced the development of magnetic field concepts, with Faraday favoring fields and Ampere focusing on forces between currents. Participants debate the implications of defining magnetic fields based on test and source currents, questioning if this approach could lead to a different understanding of field directionality. The conversation also touches on the complexities of using magnetic vector potentials and gauge transformations in defining electromagnetic fields. Ultimately, the discussion highlights the historical context and theoretical considerations that shape our understanding of magnetic fields today.

In addition to @weirdoguy's point, then, how do you define this field when two or three particles pass through the same point with different velocities? Your field has different strengths and directions from the same source at the same point.

Thank you.
Good point, I didn't think of that.
