How does the electron spins affects the magnetic field?

Click For Summary
SUMMARY

The discussion centers on the relationship between electron spins and magnetic fields, specifically how imbalances in electron spins lead to magnetism. It is established that in magnetized iron, electrons align in the same direction, creating a coherent magnetic field, while in non-magnetized iron, the random orientation of atomic domains results in a net magnetic field of zero. The concept of magnetic domains is highlighted as crucial in understanding how individual atomic behaviors contribute to overall magnetism.

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.
