Magnatism & the Things We THINK We Know About It     Magnatism is a wonderous natural phenomanon. Since days beforescientific discoveries were even written down the piece has been playing withthe theories of magnatism. In these three labs we delt with some of the sameideas which have pondered over for long before any of us were around. In theseconclusions we will take a look at these ideas and find out what exactly we havelearned.     To understand the results of the lab we must first go over the factsabout magnatism on the atomic level that we have discovered. The way magnatismworks is this magnatism is all based on the simple principle of electrons andthere behavior. Electrons move around the atom in a specific path. As they dothis they are also rotating on there own axis. This movement causes anattraction or repultion from the electrons that are unpaird. They are moving intwo directions though causing a negative and positive charge. In the case ofmagnatism though we find that these elements have a lot of unpaired electrons,in the case of iron, Fe, there are four. What happens then in the case of anatural magnet the unpaired electrons line up or the magnet in a specific mannor.That is all the atoms with unpaired electrons moving in a direction whichcauses a certain charge are lined up on one side and all the atoms with theopposite charge move to the other side. The atoms then start to cancel eachother out as they apostrophize the center of the magnet. This all happens at thecurrie point where these atoms are free to move and then when cooled and themetel becomes solid the atoms can no longer move (barely) causing a "permanent"magnet (as in the diagram on the next page). This same principle can be appliedto a piece of metal that has been seated next to a magnatized piece of metel inthat over the long time they are togather the very slow moving atoms in themetal situate in the same fassion also creating a magnet. Now that we know thebasics lets begin with the experiments.     Part one of the lab started us on our journey. In this part we took an implement with wire wrapped around it put a compass in the middle of the wirewraps. The setup was arranged so that the wraps were running parralel with themagnetic domain of the earth, that is they were north-south. With this setup we
