Sheer Magnetism Hands-on Activity for Understanding Magnetic
... Individual atoms have been discovered to have magnetic fields. For this reason, the structure of the atom itself is closely linked to magnetism. Some atomic structures, however, like those that tend to form solids, such as the metals iron, cobalt, silver, gold, and copper, are more inclined to work ...

... It is seen that the operators in S + (q) are such that a down-spin is destroyed and an up-spin is created, while in S − (q) it is the other way around. We also see that S z counts the number of up-spins minus the number of down-spins. Let us now consider a system of electrons (described by an Hamilt ...

MAGNETISM
... The difference between a piece of ordinary iron and an iron magnet is the alignment of domains. In a common iron nail, the domains are randomly oriented. When a strong magnet is brought nearby, as shown in Figure 36.9, two effects take place. One is a growth in size of domains that are oriented in t ...
