To help with your intuition you can imagine any form, filled with tiny ball magnets. Each small piece of magnet can have its own orientation of the field. There is no rule that says that macroscopic magnetic field has to be of a particular direction such as axial or radial, reason for it is pirely convinience of making such magnets.
