Ohhh look, someone has done a video with yet MORE Supporting evidence!!! Not bad sing along there too!

Yes More Evidence

Note: Roy Davis (Professional Engineer) worked with Howard Johnson also a Professional Engineer! MarkE are YOU a professional Engineer? Yet you refute an Engineers Hard Science?
You can keep posting junk that is demonstrably wrong all day long and it will not make it correct.  It just makes you look more and more foolish.

EM Junkie
here is a version our friend Johan 1955 recently sent , he also plays and thinks  outside the Box !
With "WATER FUEL".....and other things.


thanks for your contributions and sharing your work .
Chet

Chet, its a pleasure to share it! Common-sense and experiment will prevail as it did with the Flat Earth theory held for so long!

Have a good Day!

And MarkE, You can keep talking Piffle that is demonstrably wrong all day long and it will not make it correct.  It just makes you look more and more foolish.

P.S: Piffle - definition

 nonsense.
"it's absolute piffle to say that violence is ok"

synonyms: nonsense, rubbish, garbage, claptrap, balderdash, blather, blether, moonshine;

Your first problem is that the current is parallel to the field orientation.

LOL, the trouble there is that I and others have shown again and again that what we are saying is backed by 200 years of theory and experiment.  You on the other hand keep posting things as references that fail to support your loopy ideas.

MarkE, you have proven NOTHING! We all know already that Compasses work! We all know that One Iron Filing will attract another!

YOU have proven nuda, not a single thing!

Since you admit that compasses work.  And since I have shown as have thousands before me that a compass needle aligns to the local magnetic field.  And since I have shown as have thousands before me that the compass aligns parallel to a dipole near its center, then it follows that the field near the dipole center is parallel to the dipole there and not curled as you claim.  QED.

Gee, these people seem to be very definitive with this very detailed Compass Experiment!

I wonder what that big thing the show in the middle is? Did they say Magnetic Equator?

LOL, you've just posted yet another reference that is at complete odds with your claims.  Note that the compass' that lay along the equatorial projections point:  wait for it ... essentially parallel to the earth's magnetic dipole.  Note that the magnetic lines connect uninterrupted between the to magnetic poles.  Note that there is no curl from each pole to the magnetic equator.

When are you going to give up this put on act of yours?

Chris:

For the solenoid, if I can ask you to just look at just one clip, it's this one.  You will note adding and canceling magnetic field effects and how the field outside the coil loops from the north end back to the south end.  Of course it's much less dense outside the coil because it has to fill all of 3D space.

Then he uses Ampere's Law to calculate the field at the center of the solenoid. He does this by drawing an Amperian Loop to take a 'bite' out of the coil.  You then take a "walk around the loop" and do a summation to calculate the field - a closed-loop line integral.   It's a simple and elegant solution that is very easy on the difficulty scale for understanding and following integrals.

There is a part 2 but you can find it if you want to go the whole way.

Honesty, it's giving you the actual architecture of a coil.  Please look at it and see if it fits into your "world view."

Just for fun I have a 'litmus test' question for you, and the nature of this question would apply to your first pdf and other pdfs that you linked to.

These two equations describe how a coil works in an electronic circuit:

v = L di/dt

i = 1/L integral v dt

Are you familiar with them and do you understand them and ever use them?  If you understand them they give you more insight into how coils work.

I know that there is no point repeating this, but there is a wide gulf between what you "see" and what there really is.  I would hope that one day you bridge that gap.  Especially if you are interested in this stuff and have fun with it.  Like you could... Measure the value of an inductor with your scope.  Or you could measure how much energy you can store in a transformer core.  Doing things like that brings coils "down to earth" also.

I will leave you with this final thought:  When you get into your car, and put on the gas, it's like you are a coil.  lol  1/2 L i^2 = 1/2 M v^2!

Tinman EMJUNKIE has been promoting the loopy Bloch wall in the middle of a permanent magnet idea.  He's just doing a bad put-on act.

I have posted static picture sequences of mapping with an ordinary compass.  I suppose that I could hook up an analog Hall effect sensor to provide more resolution.  However I do not see the point when it should be absolutely clear that the field is essentially dead parallel to the dipole at the center when the figure eight hypothesis requires that it curls towards the dipole in that region.  If it is a question of resolution, I have lots of bar magnets and could string together a rather long composite magnet, and there will still be zero inclination of the compass to point anywhere but parallel to that structure anywhere close to the middle.  So what would be satisfactory to you?  A dipole 10X the diameter of the compass which is about what I've shown, or 20X or 50X?
Mark
Here is the problems I have with the compass test-1i have mentioned before with the two magnets with a spacer between them will show the same result, even though we know fore sure there is both poles present. The second is this-my compass needle will swing toward a magnets pole over 3 feet away insted of showing earths north/south fields.
