Because of a terrible internet connection at Mt. SAC, this is my THIRD time publishing this same post. Please excuse the fact that I lost my patience, and it is not as detailed as it originally was. 
We were given a simple DC motor in order to observe how it worked before we were to construct our own.
This is the simple DC motor that we constructed in lab. It worked very well actually.
In this demonstration, there was a current running through the rod, and we were to predict which direction the needles of the compasses would point. Of course, there is a right hand rule for such a prediction.
This is an example of a prediction for the previously described demonstration.
This was a demonstration to show that magnetic fields caused by a current carrying wire do superimpose.
