Today what worked was that we got the right magnets (strip magnets) and we also placed the magnets in the right spot which was one strip magnet on the left side of the train and the track and one on the right. We made like poles facing each other.
Today our first and second attempt failed, because we did not line it up right and the next time we learned that we had to line the magnets up better so we changed it to line up better.
My goal for the next design session is to make the train still levitate even being weighed down by weights. Another goal I have is to cooperate better in terms of who is going to hold the magnets and who is going to put the magnets in to place and if it does not work who is going to try there design next.
