In 3m we have been learning about Maglev trains. We are working on getting a car to levitate over a track with magnets. My group was arguing about what kinds of magnets to use. Two of us wanted to use bar magnets. The other two wanted to do strip magnets. We argued about safety and money because if it was for real then it would cost way more then what it would right now witch is 0. At the end we all decided to do bar. After we finished arguing we started creating. But instead of starting right away we had to plan how the magnets were going to go on the car and the track. We had to change the place of the magnets because they would not repel only because they were not lined up correctly.
