For the situation is question 1, how many elementary charges (unbalanced electrons or protons) are on the oil droplet? [Note: this is the famous Millikan Oil Drop experiment. Millikan was able to take into account the air friction and buoyant force on the droplet (which we ignore here) and solved for the total charge on the drop. By finding that the charges on many drops were multiples of a single common value, he was able to experimentally find the charge on a single elementary charge for the first time. He won the Nobel Prize for that accomplishment.]

Ising model of Ferromagnets

The Ising model is one of the easiest and most famous theoretical models for ferromagnetism in statistical mechanics. When a group of atomic spins aligns such that their magnetic moments are pointed in the same direction and produce a strong permanent magnetic moment in macroscopic size, the phenomenon is called ferromagnetism. The relative permeability of these magnets is greater than unity and increasing magnetization with the applied external field. Even in the absence of an external magnetic field, these substances retain spontaneous magnetization. An example of ferromagnets is iron.
