Mostly Permanent Magnet Motor with minimal Input Power

Thanks for your post Ron

How about a new test. Find 2 separate cores and inset one in the center of your coil and one on the outside of the coil and probe to see how the core fields compare to the coil fields.
The core may need to be higher then the coil so it's away enough that your probe won't picking up coil fields.

Thanks for your help

You are welcome.


As before a positive reading is North (no minus sign) and a minus reading is South.


Two setups, not elegant, just stuff I had laying about.


As before both, inner top face of coils N. On the E core I would have to change my drawing. as the probe shows south on the inner face of the coil from top to bottom and north outside top to bottom.

Edit: sorry, the E cores I was referring to are in a different forum!  I was thinking of dmmpower's  list

I gave up trying to teach basics to people on the forums a long time ago because it is so frustrating.  The two of you are being willfully ignorant.  You are talking to each other like you are making sense, but my feeling is that in the back of your minds both of you know that you are not making sense.  All of your problems would disappear if you both just stopped for a week and read a book or went online and educated yourselves about magnetism.  It's like the two of you are afraid to disagree with each other so you engage in a fake "dance" with each other instead.

Luc, experiments do not trump words if the experiments are interpreted incorrectly.  The people giving you advice, like myself and Poynt, did the experiments a long time ago.  We know how to apply our knowledge and you should respect that.  You end up posing questions that you should have known the answers to years ago considering how long you have been at this.  It's like you are stuck.  Once you even wanted to change all of the physics books.

You can see how your attitude is holding you back.  Both of you have ignored Poynt's comments and my comments.  It's a no-win situation for both of you unless you change your outlook.

For the two attached pictures, there is no Bloch wall between the cylindrical magnet and the attached cylindrical piece of iron.  I am telling you this with metaphysical certitude and if you disagree with me then you are crippling yourselves with willful ignorance.  One week of self-study would resolve this and both of you could come back and say, "I get it now."

The other attached picture is presumably a cutaway of Luc's transformer and the current is the same direction in every conductor.  You will get a very weak magnetic field in the center of the cross-section.  As you move towards the outer perimeter the magnetic field will get stronger and stronger.  Once you are past the perimeter the magnetic field will start to decrease in strength.  The magnetic field will look approximately like the magnetic field around a single straight current-carrying wire.  No Bloch walls anywhere.

This is my last posting because like I said I have given up on this business of trying to educate people.  You get ignored just like you guys are doing right now.  So you can ignore this and keep on faking it or get down to brass tacks and finally understand this by starting with the basics with a book or on a web site.  It all up to you guys and how you choose to use your time.

Thanks for the new core tests Ron

Your tests are confirming the field on the ends of the cores but I was hoping you would also place your probe on the core sides (like you did with the coils) to see if the cores mimic what you found in the coils.

If you did the tests and you got nothing please let me know as that would be interesting.

Thanks again for your time

Thanks Ron for the extra tests and Bloch wall Images.

So, what's your take on why an energized coil has all those pole domains compared to a magnetized bar or a permanent magnet?
