levitating magnetic track

I was looking for insight to the orientation of the magnets in these video's

They seem to have less friction than other levitating devices with guard rails, and I was hoping to make a bigger model. I assume the traveling magnet has north and south facing up and down, but the magnetic strip track I am not sure about.

I am sorry if these video's have already been discussed

Thanks for the reply.
I know they sell the model. I was hoping to understand it better, then purchase the equipment somewhere else to make a bigger model
