[QUOTE="sophiecentaur, post: 5962125, member: 199289"] You are proposing, effectively two solenoids, connected by an iron bar, joining S pole to S pole. I cannot find an image of the fields round that particular setup but the images in [URL='https://www.google.co.uk/search?q=two+bar+magnets+field&tbm=isch&source=iu&ictx=1&fir=8segeZfzYwWnSM%253A%252CjTGyv8HjdmiJBM%252C_&usg=__ZQtDG3fLdLhZq5jvjk-cYA4GbQU%3D&sa=X&ved=0ahUKEwiKu4OG9fjZAhVpD8AKHdwUC_4Q9QEINjAB#imgrc=4MHzD5Z0Oh2-pM:']this link [/URL]may give you an idea of what to expect. You will see that the lines of force that you were thinking would somehow disappear will, in fact, bend round from S to N poles. The result will not be symmetrical but those lines will still find their way from N to S, whatever you do with them. In all the possible set ups you can see, the lines are complete - sometimes going through both magnets. [/QUOTE]
