    Explain Rules
AI Thread Summary
The discussion centers on the relationship between magnetic fields and electric currents, highlighting that they are perpendicular due to Maxwell's Equations, which govern electromagnetism. The conversation delves into the underlying reasons for these equations, pointing to the universe's local U(1) gauge symmetry as a fundamental aspect. However, the participants acknowledge a lack of understanding regarding the origins of this gauge symmetry. The dialogue reflects a quest for deeper knowledge about the principles of electromagnetism. Ultimately, the discussion reveals both curiosity and the complexity of these foundational concepts in physics.

Pls point out me every body. I wish to know why does the magnetic field and current are perpendicular to each other? Or is it natural phenomena?

A. Because of Maxwell's Equations for electromagnetism.

Q. Why are Maxwell's Equations the way they are?

A. Because the universe apparently has a local U(1) gauge symmetry.

Q. Why does the universe have a local U(1) gauge symmetry?

A. I don't know. That's as "deep" as we've gotten, as far as I know.
 
That's a pretty good reply there, though I have no idea what gauge symmetry means.
