Magnet Myths and Misconceptions

[MarkE]

To try to move forward 

What Experiment has shown me:

I know the zone around the Equator is a Null or a Zero Force Magnetic Zone. Some sort of a Cancelation occurs here. At the same time there is a large repulsion force here.

That is absolutely false.

I know that Induction is much lower at the Equator.

Flux density and curl is much higher at the poles.

I know that some strange effects are visible at the Equator.

Kindly specifically identify these effects and what evidence you believe exists for them.

The Ferrofluid Experiments are un-disputable, the show effects that are visible else where in Nature, EG: Sun's filament Eruptions and so on...

It is indisputable that the ferro fluid forms patterns. Your conclusions are highly disputable.

What I believe may be possible:

I believe there may be more than one force here, one or more of which may be proportional to the Inverse Square Law URL: http://en.wikipedia.org/wiki/Inverse-square_law

Moving away from a dipole the field falls off as the inverse cube of the distance.

We know this to be true for Gravity already and Magnetic Fields are also said to already use this effect. I believe its in effect and we can see this on the Ferrofluid in the cone shaped Spikes on each Pole!

Which "effect" would that be?  Are you still referring to inverse square law?  Because it does not work for dipoles.

The Cone Shaped Spikes are a Cone Shape for a reason!

They certainly are.  You can scratch your head on that one.  Or to use an analogy: rub a balloon on your head.

If the Fields curl back in to the Equator as has been shown in many pictures

Which pictures would those be?  And why is it that we do not see any evidence of this supposed curl back from any:  Induced voltage in a surrounding coil when we move the magnet through the coil at constant velocity, or placing test dipoles around the magnet?

then the Inverse Square Law would explain why they are hard to detect here.

Well given that the inverse square law does not apply to dipoles, you are already dead in the water with that hypothesis.  Given also that you have yet to come up with evidence of this curl back at the equator that you claim you are dead on both points.

I have a picture that appears to show this but it is hard to make out and not definitive. Picture attached.

It is a nice pretty picture.  Without a definitive statement of the conditions under which it was taken, it offers no probative value.

The Spin on each field line Curling back into the Equator could be of inverse to each other! Meaning that as each Field line of each opposite Pole Curls back into the Equator, the Vector potential of each Field Line would have a Spin in the opposing direction to each other and thus cancel each other in their close proximitys.

This is so much gobbeldygook.  Kindly define what you mean by spin on a field line.  Kindly what you are using to define discrete field lines and how to count them.

Experiment can show this effect by moving two Permanent Magnets in opposite directions relative to a stationary conductor - Null Induction. Also Bi-Filar NON Inductive Coils, not being inductive because the Spins mostly cancel to each other.

There are many ways to end up with net zero induced EMF.  Inducing two equal and opposite voltages is one such way.

Please Note: https://www.youtube.com/watch?v=r38qMrjrSqs

What you call a Bloch wall in the video you utterly and completely fail to show is in fact a Bloch wall.  What you manage to show is that a soft iron device, your pointer is pushed / pulled so as to minimize the path reluctance.  There should be no surprise that means there is a strong non-linear distribution of force that favors the poles.

In my video, the Magnetic Viewing Paper show the same effects as the Ferrofluid - The Bloch Wall Grows the longer the Magnet

Howard Johnson's work is supported by many other Magnetic Viewing Experiments today but I can not prove this is whats going on, I can prove Experimentally that the Bloch Wall is there and it can be felt and seen also with the right equipment it can be measured!

Howard Johnson never successfully closed the loop.  He basically made oversized SMOTs, which like all SMOTs were never overunity.

Ohhhhh = MarkE I am very disappointed in your reply!


Yet again - you prove one thing that has nothing to do with the topic at hand - I will leave you scratching your head on what that might be!

I think you might be a bit sad for coming this far and still having no Scientific Evidence to the Contrary? You STILL have an Orange sitting beside you and your apple is shown to be a bad one!

When you swipe an inductor past the north end of a magnet, you obtain a strong pulse of polarity x. When you swipe the inductor past the south end of the same magnet, you obtain a pulse of roughly the same magnitude, but polarity y (the opposite to x), correct?

Can you surmise why when you swipe the inductor across the middle of the magnet you obtain little to no pulse amplitude?

Yes,because it is like i said,the field changes from X to Y,so my statement is correct when i say that the field left of the dipole center is different to that of the right of the dipole center. So the field is not a uniform field,infact the field is opposite. And the field at the center that is suppose to be of the highest density produces no power at all when swipped across an inductor. This field that is suppose to be there is a nothing field-it dosnt attract feromagnetic material,and it dosnt produce any power when passed across an inductor. Then there is the big iron filings rubbish,when all of a sudden iron filings now stick to this field that has no attraction to feromagnetic material,and produces no flux through the core of an inductor-->but is the largest flux field around a magnet

You see poynt-it just makes no sense. How can one of you top notch guys say-Quote:When you swipe an inductor past the north end of a magnet, you obtain a strong pulse of polarity x. When you swipe the inductor past the south end of the same magnet, you obtain a pulse of roughly the same magnitude, but polarity y (the opposite to x),
And then we get from another top notch guy saying Quote: This is wrong.  The field is fundamentally the same.  The center of the dipole will have the highest strength field, but the direction of the field does not change.

So we got one bloke saying we have an X and Y field,and another saying this is wrong,the field is the same,the direction dose not change.
Direction of what?--is this another man made muddle up?,and how can it not change if each end of the magnet produces the opposite sine wave output when the magnet approaches and leaves the core of an inductor?.

As far as the iron filings go,they do nothing more than build a path for the magnetic flux to follow. And the strange thing about this is,you can shape those iron filings how ever you want them on the paper on top of the magnet,and they will stay there--aint that a hoot.

   Guys,
          for a bit of fun look what's going on with ,say, a horseshoe!
  At one time they were extensively used in magnetos and generators.
   I sent a post to the wrong thread.
   Inverse square works for monopole.
   For simple dipole inverse cube suits better .

Yet again you offer no facts.  The mag paper you use does not turn bright because it lays over a Bloch wall.  It turns brighter where the field lines run parallel the plane of the paper.  So we have you once again offering claims for Bloch walls where your evidence fails to support such claims.
