Discussion Overview

The discussion revolves around the existence and theoretical implications of magnetic monopoles, exploring both physical and mathematical explanations for their absence. Participants delve into concepts related to angular motion, charge isolation, and historical experiments aimed at detecting monopoles.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Historical

Main Points Raised

  • Some participants suggest that magnetic fields arise from angular motion, leading to the formation of two poles, while others argue that this does not rule out the existence of monopoles.
  • There is a proposal that a deep, unknown mechanism may prevent the existence of magnetic monopoles, rather than them being inherently impossible.
  • A participant mentions the theoretical possibility of a particle producing a radial magnetic field, which would be indicative of a monopole, contrasting with the closed field lines typically associated with dipoles.
  • Historical experiments, such as those conducted by Louis Alvarez, are referenced as attempts to find magnetic monopoles, but they were unsuccessful.
  • Speculative hypotheses regarding the origin of magnetic monopoles in the universe are discussed, with an acknowledgment that these ideas lack experimental verification.
  • One participant highlights Dirac's theoretical work suggesting that if monopoles exist, they could explain the quantization of electric charge.

Areas of Agreement / Disagreement

Participants express a range of views on the existence of magnetic monopoles, with no consensus reached. Some propose theoretical frameworks while others emphasize the lack of experimental evidence.

Contextual Notes

Participants note that the discussion includes speculative ideas and hypotheses that are not experimentally verified, and there are references to limitations in current understanding and detection methods.

Does anyone knows how to explain (both physics and mathematics) why there's no magnetic mono-pole?
 
Physics news on Phys.org
Physics can alone do that job.



M.F arises cause of angular motion mostly, and the character of angular motion is that from one side it looks like tuning clockwise and the other side anticlockwise.

As a result you get 2 poles.

Similar can be said about a charged particle in leaner motion; from one side its direction is left, from the other its right.
 
They are not ruled out by either.

They just haven't been found yet, or there is some deep, unknown mechanism which prohibits them from existing.
 
You mean what I've said yet unknown?

What i mean is: compare with the charge (Q), which is can isolate to mono-pole ( +Q or -Q ), and we can interpret each behavior separately.
 
I recall hearing about Louis Alvarez (Nobel Lauriate) grinding up meteorites found in Antartica and making marbles out of them, and spinning them inside toroidal solenoids using compressed air to search for a dc current in the coil. No luck.

You are referring to magnetic fields that arise due to some electrical current. as a result, the magnetic field lines are closed and you always end up with a dipole. It is, however, also possible (at least on a theoretical basis) to constitute a particle which produces a radial magnetic field. Such a field cannot possibly be generated by a dipole source. The source is in fact a monopole.

Magnitude is not the reason here.

Sorta, but I considered spin too (with an electron).
 
I believe there are some possible hypotheses regarding magnetic monoples at the origin of the universe...I can't recall the brief commentary I have seen but my recollection is that it was speculative..certainly nothing is known for sure nor experimentally verified...

Wiki has a nice write up at

http://en.wikipedia.org/wiki/Magnetic_monopoles
" Dirac showed that if magnetic monopoles exist, then that would explain the quantization of electric charge in the universe..."

"These theories are not necessarily inconsistent with the experimental evidence: in some models magnetic monopoles are unlikely to be observed, because they are too massive to be created in particle accelerators, and too rare in the universe to wander into a particle detector."
