Magnatism & The Things We Think We Know About It!

Magnatism & the Things We THINK We Know About It!

Magnatism is a wonderous natural phenomanon. Since days before

scientific discoveries were even written down the world has been playing with

the theories of magnatism. In these three labs we delt with some of the same

ideas which have pondered over for long before any of us were around. In these

conclusions we will take a look at these ideas and find out what exactly we have

learned.

To understand the results of the lab we must first go over the facts

about magnatism on the atomic level that we have discovered. The way magnatism

works is this: magnatism is all based on the simple principle of electrons and

there behavior. Electrons move around the atom in a specific path. As they do

this they are also rotating on there own axis. This movement causes an

attraction or repultion from the electrons that are unpaird. They are moving in

two directions though causing a negative and positive charge. In the case of

magnatism 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 a

natural 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 which

causes a certain charge are lined up on one side and all the atoms with the

opposite charge move to the other side. The atoms then start to cancel each

other out as they approach the center of the magnet. This all happens at the

currie point where these atoms are free to move and then when cooled and the

metel 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 applied

to a piece of metal that has been sitting next to a magnatized piece of metel in

that over the long time they are togather the very slow moving atoms in the

metal situate in the same fassion also creating a magnet. Now that we know the

basics lets begin with the experiments.

Part one of the lab started us on our journey. In this part we took an

apparatus with wire wrapped around it put a compass in the middle of the wire

wraps. The setup was arranged so that the wraps were running parralel with the

magnetic field of the earth, that is they were north-south. With this setup we
