SUMMARY

The discussion centers on the relationship between magnetic fields and electric currents, specifically addressing why they are perpendicular to each other. This phenomenon is explained through Maxwell's Equations, which govern electromagnetism. The conversation further delves into the underlying principles of these equations, highlighting the concept of local U(1) gauge symmetry as a fundamental aspect of the universe. However, the discussion concludes with an acknowledgment of the limits of understanding regarding the origins of this symmetry.

PREREQUISITES
  • Understanding of Maxwell's Equations in electromagnetism
  • Familiarity with gauge symmetry concepts
  • Basic knowledge of electromagnetic fields
  • Awareness of fundamental physics principles
NEXT STEPS
  • Research the implications of Maxwell's Equations in modern physics
  • Study the concept of gauge symmetry in quantum field theory
  • Explore applications of electromagnetism in technology
  • Investigate the historical development of electromagnetic theory
USEFUL FOR

Physics students, educators, and anyone interested in the fundamental principles of electromagnetism and their applications in technology and theoretical 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.
