Magnetic field lines of a moving electron

Click For Summary
SUMMARY

The discussion focuses on the magnetic field lines produced by a moving electron, specifically addressing both linear motion and the effects of intrinsic spin in hydrogen electrons. Participants seek visual representations akin to bar magnet field lines and explanations of these phenomena. Additionally, the conversation touches on drift velocity in superconductors, noting that while typical drift velocities in household electrical wires are around 0.05 mm/s, superconductors exhibit virtually zero resistance, implying higher drift velocities for electrons. This highlights the unique behavior of electrons in superconducting materials.

PREREQUISITES
  • Understanding of electromagnetic theory, particularly magnetic fields.
  • Familiarity with quantum mechanics, specifically electron behavior and spin.
  • Knowledge of superconductivity and its implications on electron movement.
  • Basic grasp of drift velocity concepts in electrical engineering.
NEXT STEPS
  • Research the magnetic field lines of moving charges using Maxwell's equations.
  • Explore visualizations of electron spin and its magnetic effects in quantum mechanics.
  • Investigate the properties of superconductors, focusing on electron drift velocity and resistance.
  • Learn about the applications of superconductivity in modern technology, such as MRI machines and particle accelerators.
USEFUL FOR

Physicists, electrical engineers, and students studying electromagnetism and quantum mechanics will benefit from this discussion, particularly those interested in the behavior of electrons in various states of motion and the implications for superconductivity.

A moving electron's magnetic field lines.

How do the magnetic field lines of a moving electron in a straight line look? What about the magnetic field lines of a rotating hydrogen electron? I mean the magnetic field produced due to the electron's intrinsic spin and due to its movement in a line or around an atom. I have searched this forum and the internet and I couldn't find a picture or explanation. Does anyone have a link to a nice picture of this, like that of a bar magnet's magnetic field lines, or a good explanation?

Another perhaps more simple question I have is: what is a common drift velocity observed in a superconductor? I know its very low in the electrical wires in our house for example (0.05 mm /s ). I read that in a superconductor the resistance (which as I understand is caused by electrons colliding with atoms) is virtually 0. So I assume the drift velocity of electrons in a superconductor is relatively high.
