Chloe hung three metal bars, E, F and G, from a rod as shown below. She labelled the two ends of each metal bar, A and B. She then brought a bar magnet close to each end of the metal bar and recorded her observations on the interactions between the metal bars and the bar magnet.
Her observations are shown in the table below.
|Magnet and End A||Magnet and End B|
|F||no interaction||no interaction|
Which of the following could E, F and G be?
