B Induced magnetism

  1. Feb 10, 2017 #1
    I have been trying to search for answers on the Internet, but to no avail.
    For induced magnetism, i understand that a magnetic material can turn into an induced magnet under the influence of a magnetic field. However, i do not understand how to magnetic poles are determined.

    Suppose a perm magnet arranged as SN. a magnetic material is placed to its right. Why is the induced S pole at the centre with 2 N pole on the ends of the material?
    Shouldn't the induced magnet have a N on the left side and S on the right side? Why is the N at the centre? I can't find a diagram sorry

    That doesn't look right. If this was the case, the field lines inside the material would not be unidirectional.
    Can you upload the picture? You can take photo of it and post it here using the upload button below the editor space.
