How does the electron spins affects the magnetic field?

Click For Summary

Discussion Overview

The discussion centers around the relationship between electron spins and magnetic fields, exploring how electron spin imbalances contribute to magnetism, particularly in materials like iron. The scope includes conceptual understanding and technical explanations related to magnetism.

Discussion Character

  • Conceptual clarification, Technical explanation, Debate/contested

Main Points Raised

  • One participant suggests that an imbalance in electron spin is known as magnetism, noting that in magnetized iron, electrons are aligned in the same direction, while in non-magnetized iron, they are unbalanced in different directions.
  • Another participant agrees with the previous claim, reinforcing the idea that electron imbalance causes magnetism.
  • A different viewpoint introduces the concept of magnetic domains in iron, stating that these domains produce coherent magnetic fields individually, but the overall magnetic field of non-magnetized iron is zero due to random orientation of the domains.

Areas of Agreement / Disagreement

Participants express agreement on the role of electron spin in magnetism, but there is a divergence regarding the explanation of magnetic domains and their contribution to the overall magnetic field in non-magnetized iron.

Contextual Notes

The discussion does not resolve the complexities of how electron spins and magnetic domains interact, nor does it clarify the assumptions regarding the behavior of electrons in different states of magnetization.

how does the electron spins affects the magnetic field??

help needed...tks in advance :smile:

I'm pretty sure if there is an imbalance in electron spin that is commonly known as magnetism. In a magnetized piece of iron each atom has it's electrons unbalanced in the same direction. In a nonmagnetized piece, they are all unbalanced, but it's different for each atom. Magnetism is caused by moving charge that's why it's caused by electron imbalance.
 
the dude is right.
 
In a bulk of iron, don't the atoms group together in large (compared to the atoms) cells called domains? I thought that the domains individually produce a coherent magnetic field, but the net magnetic field of a non-magnetized piece of iron is zero because the domains are randomly oriented.
