Discussion Overview

The discussion revolves around the nature of magnetisation and its relationship to moving charges. Participants explore whether magnetism should be studied independently or fundamentally through the properties of charges in motion, particularly in the context of educational approaches to electromagnetism and condensed matter physics.

Discussion Character

  • Debate/contested
  • Conceptual clarification
  • Technical explanation

Main Points Raised

  • One participant asserts that magnetisation is fundamentally a situation of moving charges and questions the rationale behind studying magnetism as a separate entity.
  • Another participant argues that magnetism is indeed studied at a fundamental level, particularly through atomic and electronic interactions in condensed matter, suggesting a misunderstanding of the original question.
  • A third participant references Maxwell's work, indicating that while magnetism and statics can be described by a unified theory, they are not identical, and questions the separation of these topics in educational contexts.
  • A later reply emphasizes that not all magnetism arises from moving charges, pointing out that individual particle spins in condensed matter do not involve moving charges, thus complicating the notion of studying magnetism solely through that lens.

Areas of Agreement / Disagreement

Participants express differing views on the independence of magnetism as a subject of study. There is no consensus on whether magnetism should be approached through the lens of moving charges or if it warrants its own study, indicating ongoing disagreement.

Contextual Notes

Some assumptions about the definitions of magnetism and its relationship to moving charges remain unresolved. The discussion highlights the complexity of magnetism in different contexts, such as condensed matter physics, which may not align with the initial premise of moving charges.

It is established that magnetisation is a dynamical situation of moving charges. Hence it is not an independent phenomena. But why keep on studying magnetics by itself? For example, search for magnetic monopoles, magnetisation of objects? Shouldn't we study it at a fundalmental level using properties of charges when in motion instead?

But we do study magnetism at it's most fundamental level. That being the level of atoms and electrons and their interactions in condensed matter. Your question is a bit unclear to me and maybe I'm missing your point?
 
maxwell proved that magnetics and statics are the same, therfor the op asks why do we separate the two in some courses, when we could just learn electromagnetics.

That doesn't make any sense either.

While they can be described by a consistent, single theory, they are not "the same". That's like asking why can we just study "acceleration" rather than force since they're "the same"?

Note that not ALL magnetism are generated by "moving charges". As inha as mentioned, the study of magnetism, especially in condensed matter does not involved moving charges. Individual spins of particles are not due to such a thing. You simply cannot transform such a description away and deal instead with moving charges.
