The rails in Fig. 3 each have a resistance of 2.2 12/m. The bar moves to the right at a constant speed of 9 m/s in a uniform magnetic field of 0.8 T. Find I(t), 0<t<1 s, if
the bar is at x = 2 m at t=0,if
(a) a 0.3 resistor is present across the left end with the right end open-circuited
​

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
