It's cool looking, not its not magical or exotic.
If you want to see something really, really cool, watch this video:
But don't be fooled by the word "levitates" in the video descriptor. What you will see is "Quantum Levitation of a Super Conductor". and "Quantum Locking" It's 10 minutes long but really worth watching if you like cool science.

Yeah... that was cool. From what I could understand he created a magnetic field, then cooled a lesser metal which had a bit of a magnetic field which locked it. Something like that.
I'm not sure what high school is doing electric motors with neo magnets. Notice how the setup in my video has no full circuit connection? I am not a motor builder by any stretch of the imagination but I remember doing some fun little tests way back but am fairly certain it included a copper wire connecting both the negative and positive of the battery to make it work.
Also, if I were to flip the magnets, it would spin the other direction. That is rather obvious though since you are changing the polarity.
