Relation between electricity and magnetism?

Click For Summary
SUMMARY

The discussion centers on the relationship between electricity and magnetism, specifically addressing how flowing current in a wire generates a magnetic field. Participants argue that this phenomenon is primarily a relativistic effect rather than a quantum mechanical one. The role of the electron's spin quantum number and its wave nature is debated, with some asserting that the dual nature of electrons does not significantly impact magnetic fields. Key references include materials from Weber State University and Mount Holyoke College, which provide insights into the electromagnetic principles involved.

PREREQUISITES
  • Understanding of classical electromagnetism principles
  • Familiarity with relativistic effects in physics
  • Basic knowledge of quantum mechanics, particularly electron behavior
  • Awareness of the concept of spin quantum number
NEXT STEPS
  • Research the relativistic effects on electromagnetic fields
  • Study the principles of classical electromagnetism using resources like "Introduction to Electrodynamics" by David J. Griffiths
  • Explore the implications of quantum mechanics on electromagnetic theory
  • Investigate the validity of the dual nature of electrons through academic papers and articles
USEFUL FOR

Physicists, electrical engineers, and students studying electromagnetism and quantum mechanics who seek a deeper understanding of the interplay between electricity and magnetism.

Why flowing current in wire creat magnetic field...if anybody say this is because of spin quantum number,...
So i just want to say spin quantum number is because of wave nature of electron.i just want to know what effect of dual nature of electron on magnetic field.:rolleyes:

Its got nothing to do with QM - its a relativistic effect:

The deep reason for both electricity and magnetism however is quantum:

This dual nature wave particle stuff is a myth:
