how does the electron spins affects the magnetic field??
help needed....tks in advance
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.
