It does appear that a magnet either cannot be magnetized to generate a circular field or the field simply is contained inside the magnet.

Logically, the field is simply retained within the core the same as connecting several magnets to form a ring or even placing a keeper on a magnet and retaining the field within the magnet.

Just pondering why a conductor is so different I might think that a field is generated in the conductor core which pushes the moving electrons outward to the skin of the wire where another field is generated outside the wire in the air.

One field inside pushing electrons outward, another field outside expanding into the air.
If this were true it would be impossible to generate the same field by permanent magnets.

Why don't you try using a lower coercivity material?  If the idea is to find out whether something can be magnetized to emulate the field that surrounds a wire, then a piece of iron or steel rod may be the way to go.  Then you can do an iron filing pattern test to see if the field persists as it should even though it will be weak.  Other experiments could include running a wire much longer than the diameter of a washer through the middle, and then energizing and deenergizing the wire.  The other thing that you should watch out for is that your magnetizer current doesn't oscillate thereby making something of a degausser.  A fast diode across the wire ends should take care of that.

I am reasonably convinced that the field generated by current flowing in a conductor is unique and is impossible to emulate with magnets.
However, a new discovery on making non-magnetic metals magnetic, indicates it may be possible from the following quote:

"In the new study, the researchers have shown how to change the exchange interaction and DOS in non-magnetic materials by removing some electrons using an interface coated with a thin layer of the carbon molecule C60, which is also called a 'buckyball'. The movement of electrons between the metal and the molecules allows the non-magnetic material to overcome the Stoner Criterion."


So it seems that if a thin layer with magnetic properties could be formed with the right field direction on the outside of a non-magnetic metal, it may be possible to build a non-electrical wire that simulates a wire with a current flow.

Magnetization is just the process of aligning domains.  Since domains can take on any orientation, there is no reason that I can think of as to why you should not be able to magnetize circularly except right at the center of a disk.  I think that the problem you have magnetizing hard magnetic material is one of developing enough field strength.  That is why I am suggesting you experiment with relatively low coercivity materials to start.  Just eliminate reaching saturation flux as a requirement to start.  Assuming that you successfully magnetize circularly, as I think you should be able to do, then it would become a matter of engineering a magnetizing rig that develops an sufficiently intense field to magnetize the hard magnetic materal.

Here is a reference on defect detection using both circular and longitudal magnetization:  https://www.nde-ed.org/EducationResources/CommunityCollege/MagParticle/Physics/FieldOrientation.htm

My potential solutions to  the  'non-electric-faraday-motor'

Solutions
( 1 ) -  The  interaction in the  'First-Image'  I have attached below,  and applied in the ways below ( or combined with them ).

( 2 ) - The way  the  'non-electric-railguns' work,  but I thought I had seen one in which the  interacting  magnets were  90-degrees to each other,  but I cannot find it now.   (  but the angles of standard   'non-electric-railguns'  could work as well,   remembering,   the  static magnets  in the    'non-electric-railguns'  I have seen are all the same strength and angle,   perfect  )

(  I also  visualized  this solution  as a combination of the  two-rings( or 3 rings in my  Levitating-Object-Invention )  and my latest  New-Type-of-Magnetic-Bearing-Invention  )

(  I'm  not sure why I prefer the interaction of magnets at  90-degrees  to each other,  rather than other angles  )

(  And,  in a solution,  one or more of the interacting  magnetic-surfaces  might be made into  a brick-wall type pattern ,  and it would actually look like a standard  brick-wall pattern,  in order to get past  sticky points  )

The  second image ,   I have attached below,  another configuration and interaction I have found usefull for this problem

(  P.S. This site needs a  'function'  that when a   'Required-Scientific-Explanation'  is  'identified'  by it's  members,  and if it is deemed  important enough by a   'Person-Appointed-for-the-Function',    that then  the  'Person-Appointed-for-the-Function'  ensures that the  'Required-Scientific-Explanation'  is obtained from  appropriate sources.     The best example is this  'non-electric-faraday-motor'  problem .    Earlier,  I had noticed indications that  qualified  physicists( or from other fields ) do actually know the answer to this question (  although some think the explanation is too complicated for the members in this site too understand .   It's sad that members here are wasting their valuable time and materials and their energy in  'quasi-daft'  or  'overly complex'  attempted  solutions to an incredibly simple  problems,  that could be prevented from happening if they had  the  existing  'correct-scientific-answers'  from the correct sources .   )
