How does the electron spins affects the magnetic field?

In summary, the presence of an imbalance in electron spin results in magnetism. This is seen in a magnetized piece of iron where all atoms have their electrons unbalanced in the same direction. In contrast, a non-magnetized piece of iron has randomly oriented domains which individually produce a coherent magnetic field, but the net magnetic field is zero. This is because the atoms in a non-magnetized piece of iron have different electron imbalances. The movement of charge, specifically the imbalance in electron spin, is the cause of magnetism.

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.
 

What is an electron's spin?

An electron's spin refers to its intrinsic angular momentum. It is a fundamental property of all subatomic particles and is a form of intrinsic magnetism.

How does an electron's spin affect the magnetic field?

An electron's spin creates a magnetic moment, which contributes to the overall magnetic field of a material. This magnetic moment can align with an external magnetic field, causing the material to become magnetized.

Can an electron's spin change?

An electron's spin is a constant property and cannot change. However, the direction of the spin can be influenced by external magnetic fields or interactions with other particles.

How does the spin of multiple electrons affect the magnetic field?

The combined spins of multiple electrons within a material can create a stronger magnetic field. This is the basis for ferromagnetism, where the aligned spins of electrons create a macroscopic magnetic field.

Can the spin of an electron be measured?

Yes, the spin of an electron can be measured through various techniques such as electron spin resonance or spin-polarized scanning tunneling microscopy. These methods allow for the detection and manipulation of the electron's spin state.
