The magnetic moment of atoms in a ferromagnetic material cause them to behave something like tiny permanent magnets. They stick together and align themselves into small regions of more or less uniform alignment called magnetic domains or Weiss domains. Magnetic domains can be observed with a magnetic force microscope to reveal magnetic domain boundaries that resemble white lines in the sketch. There are many scientific experiments that can physically show magnetic fields.
When a domain contains too many molecules, it becomes unstable and divides into two domains aligned in opposite directions so that they stick together more stably as shown at the right.
When exposed to a magnetic field, the domain boundaries move so that the domains aligned with the magnetic field grow and dominate the structure as shown at the left. When the magnetizing field is removed, the domains may not return to an magnetized state. This results in the ferromagnetic material's being magnetized, forming a permanent magnet.
When magnetized strongly enough that the prevailing domain overruns all others to result in only one single domain, the material is magnetically saturated. When a magnetized ferromagnetic material is heated to the Curie point temperature, the molecules are agitated to the point that the magnetic domains lose the organization and the magnetic properties they cause cease. When the material is cooled, this domain alignment structure spontaneously returns, in a manner roughly analogous to how a liquid can freeze into a crystalline solid.
Sometimes the group can become the leader

A "leader" is the last thing a public voice of this size needs. This is about ALL corruption on ALL levels of the business and government, and if a person steps forward, to try and lead this movement, his/her personal views will become the headwater of public opinion on the entire group, which could paint this thing in a bad light. We've already got a goodly number of misinformed people who believe Communist and Fascists speak for the majority, which they do not. Imagine if the a questionable leader rose to become the voice of the Occupy movement.
The it stands now, anyone with a grievance can step forward to voice their concerns and ideas. A leader would add a dimension to this movement's growth that would be both biased and segregative.

I nominate you for the Talking out of my Butt award. congratulations, the cheque is in the mail, and the complimentary gift basket full of fluoridated water, diet coke with aspartame, and some nice BPA plastic containers, is also in transit to your location.
Anyways, how is that unjust sense of self satisfaction working for you?
And when the time comes, I'll vote for this person as president.
I also disagree with a leader they can be corrupted or manipulated
Who cares if there is no central agenda for them to pick apart
