Permanent magnet motor

[lumen]

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

Interesting page but what they show is with current flowing to test the anomalies at the imperfections in the weld.

What I'm saying is that without the current flowing, the field attracts into the core and becomes locked in it's own reinforcing loop.

If you connect several diametrically magnetized cylinders into a ring, they suddenly become very non-magnetic even though nothing has changed within the magnet and it is still fully magnetized, the field remains in the core.

When the loop is broken the field returns as expected. So even if one did achieve a circular field in a cylinder, you would never know because it would loop only inside the core.

That's why current flow generates a special case where the field is excluded from the core or is pushed outside of it.

What you have just   highlighted  about the   viability   of a  magnetic ring ( the same fact I keep on forgetting, and remembering )  ,     makes  me realize  that if you sufficiently space out the magnets in the magnetic ring( in order to retain their magnetic-field )  ,   then  the  two-rings( or 3 rings in my  'Levitating-Object-Invention' )  could function successfully  or  semi-successfully,   and an unwanted  cog-wheel-frictional-effect  could  be eliminated by many  multiple  inner and outer  'magnetic rings',  overlapping each others cog-wheel-frictional-effect .

Spacing the magnets will cause some of the field to be exposed but then the second problem arises, the circular field is no longer continuous but broken allowing merge points for the external field to attract into.

In a conductor the field is continuous and another parallel field is unable to merge into it so there is no attraction, unlike the broken field where a parallel field will attract into the broken spaces causing attraction unlike the conductor.

Yes,  but I was only talking about how it could solve my   invention  in another  thread  .

______________

Regarding  :  The  Non-Electric-Faraday-Motor

(  The Following Would Not Work,  But I Should Type It    :    Imagine  this  'magnetic-ring'  made  of  spaced  strong-magnets,  you could then enclose  this ring in an outer shell made of some type (  or pattern ) of material,  that  could smooth out the field,      'But Then the Field in The Outer Shell Would Would Remain Inside The Outer Shell Material Because it is a Ring'    )

A Good Solution Could Be To Arrange The Magnets In  a 'Brick Wall Pattern'
The   'spaced-magnets'  could be arranged  in a   'Brick-Wall'  pattern,     to   'counter-balance'   each others    'Merge Points' ,  so that those  'Merge Points'   do not stop rotation.
(   And,  this  'Brick-Wall' effect,   to   'counter-balance'   each others    'Merge Points',   could be achieved in other ways,  such as multiple wheels  all  spinning on the same  axle,   and there are also other ways   )

And, we've done a full circle to return to the common problems in magnet-motors

Another  possible  solution to achieve the  'replication'  of  the  'magnetic-field'  of an  electric-wire( carrying DC current )  by just using   'permanent-magnets',    for the   'Non-Electric-Permanent-Magnet-Powered-Faraday-Motor'   .

In the image below,  is a  drum  covered in the blue magnets .

(  But the drum could be without the magnets,  and be replaced  with a  cylinder-shaped-magnet   ) .

Around the drum,  is the  'Coiled-Magnet' .
(     One way to make an 'almost' equivalent of a  'Coiled-Magnet' ,  could be to,  for example,  get a small-flattish-round-magnet,  then join a short section of  'Coiled Metal' to it,  and repeat this process until the coil is long enough,  and maybe you could fit what you've made into  a  Coiled-Pipe,  so that it doesn't collapse  )  .

The drum ( or magnets on the drum ),  will  never  detect  either end of the coil ( the  merge-points )  .
