Discussion Overview

The discussion revolves around the generation of magnetism at the subatomic level, specifically focusing on how magnetic fields are produced around electrons. Participants explore concepts related to electromagnetism, angular momentum, and the intrinsic properties of electrons, seeking a deeper understanding of these phenomena without relying on established equations like Maxwell's equations.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • Some participants question how magnetism can be derived from electricity at the subatomic level and seek a deeper understanding of the magnetic field generated around an electron.
  • One participant argues that electromagnetism is a single phenomenon and that physics cannot definitively describe "how" magnetism occurs, only provide models that agree with experimental observations.
  • Another participant states that the angular momentum of an electron is an intrinsic property and does not imply that the electron spins faster than light, clarifying that the magnetic field is another aspect of the electromagnetic field.
  • There is a suggestion that a moving electron generates a magnetic field due to electric current, independent of its angular momentum.
  • Questions arise regarding the production of the magnetic dipole around the electron, with some participants indicating that there is no meaningful way to answer this question, similar to inquiries about the electric field around an electron.

Areas of Agreement / Disagreement

Participants express differing views on the nature of magnetism and the intrinsic properties of electrons. There is no consensus on how to definitively explain the generation of magnetic fields or magnetic dipoles around electrons.

Contextual Notes

Participants highlight limitations in understanding the fundamental mechanisms behind magnetism and electric fields, indicating that these concepts may not be fully resolvable within the current frameworks of physics.

how can magnetism be derived from electricity at the sub atomic level??
how is the magnetic field generated around an electron?

if magnetism is just generated due to angular momentum of the electron it is said that if calculated the spin of electron would exceed light speed ; so will it work even in this condition when spin is greater than speed of light
please answer genuinely and don't give me maxwells equations
(i need to understand this in a deeper level)

I don't think this is a useful view.

Electromagnetism is one phenomenon. Sometimes (but not in general) you can split it in separate parts and call them "electricity" and "magnetism".

how is the magnetic field generated around an electron?
Physics cannot describe "how". It can provide models in agreement with experiments - with concepts like electromagnetic fields - but it cannot say "how" something "really" happens on a fundamental level.

if magnetism is just generated due to angular momentum of the electron
It is not. The statement is too vague to be more specific here.
so will it work even in this condition when spin is greater than speed of light
Spin does not have a speed.

please answer genuinely and don't give me maxwells equations

Quantum electrodynamics is the next deeper level (and way more advanced and complicated), but you'll see the same thing again: we observe things and then we make theories to agree with those observations.

I'll answer obliquely with another question: how is the electric field generated around an electron
if magnetism is just generated due to angular momentum of the electron it is said that if calculated the spin of electron would exceed light speed ; so will it work even in this condition when spin is greater than speed of light
please answer genuinely and don't give me maxwells equations

Forget about the electron spinning faster than light. The electron's angular momentum is an intrinsic property of the electron. Just as an electron carries mass and electric charge, it also carries angular momentum and a magnetic dipole. None of this requires the electron to move faster than light. None of this requires the electron to move at all. The electron isn't actually physically spinning around itself. The Magnetic field is just another aspect of the electromagnetic field. If you have no problem with the electron generating an electric field, than you should have no problem with the electron generating a magnetic field.

Now, said that, you also have to realize that even if the electron had not a magnetic dipole it would still produce magnetic fields because a moving electron causes electric current which will generate a magnetic field.

then how is the magnetic dipole produced around the electron?

Please read the previous two posts again, there is no meaningful way to answer this - in the same way you cannot answer the question from dauto: "how is the electric field generated around an electron"
