A rectangular loop of wire is placed next to a straight wire, as shown in the (Figure 1). There is a current of I = 2.5 A in both wires.
Determine the direction of the net force on the loop.
Determine the magnitude of the net force on the loop.

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
