Answer to Question #164982 in Physics for Maria Roman

Question

which magnet configuration do you think would make a better design for a real train car system; thr one that uses a north south magnetic configuration or the one that uses a borth north magnetic configuration?

Answer 1

Depends on the context. However, the configuration with both north poles is better for magnetic levitation or propulsion because they repel. North-south would eventually stick to each other.
