Nine identical wires, each of diameter d and length l, are connected in parallel. the combina- tion has the same resistance as a single similar wire of length l but whose diameter is:

Part 1: a magnetic levitation or maglev train rides rails without touching them. explain how this works using your data. include the appropriate magnet drawing in your answer. part 2: two objects are near a bar magnet. one is about 1 cm away, while the other is 6 cm away. compare and contrast the magnetic force that affects each object. use your data to answer the question
