Christ, these people have confused magnitude for direction.  Optical illusion "leads out" massive delusion.

Looks like they aren't the only ones doing that. Funny how iron filings don't show that pinch at the waist, isn't it.

I can also provide experiment to show this.

EXPERIMENT: "Coriolis Effect"

1: Replicate the "Coriolis Effect" expreriment in the above Video and record your Direction of Spin!
2: Place a LARGE Magnet under your Funnel with a reasonable Gap under the Spout so as to not impede the flow of water but not too far so the Field of the Magnet is too far away.
3: Replicate the "Coriolis Effect" experiment with the control Magnet under your Funnel.
4: Flip your Magnet over and Replicate again.

Result:
You will see the Direction of the "Coriolis Effect" change depending on the Polarity of the Magnet to the Polarity you are on the Earth.

The Bloch Wall Exists!

Iron Filings are a VERY Bad control and should not be used! They only are used by amateurs that simply don't know any better!

Reason: it's the same as two wires carrying current in the opposing directions can not lay parallel together! The Spins repel each other. As a result they are repelled from each other! This means the take an alternate path. That's why Iron Filings are So Much Denser on the Poles that in the centre of the Magnet!

Experiments with the Coriolis Effect can also prove that there is a Bloch Wall.

The "Coriolis Effect" should be enough for most to prove that the Bloch Wall Exists!

Okay for starters, how can the existence of the Coriolis Effect prove there is a Bloch Wall?  They are two separate things with no relation to each other.  I actually do realize where it is coming from, because in your other clip they show the "curling (magnetic?) field" inside a bar magnet and so curling stuff inside a magnet equals the curling Coriolis Effect... or does it?  Who says there has to be any relationship at all?  More importantly, there are no curly magnetic fields inside the magnet.

The clip where the guy crosses the equator to demonstrate the draining water changing directions is just for show for tourists to make a bit of money.  My analog computer in my brain is telling me that it is not true because the forces at play are so minimal that they will be less than the random motion of the water molecules and currents from pouring the water into the drainage bowl in the first place.  It just a variation on slight of hand to amuse the tourists.  Yes of course the Coriolis Effect is real, but you have to be more than a few feet from the equator for it to take effect.  The important lesson there is to understand proportion and when things are significant and when they are insignificant.

Quote
I hope your Imaginary argument of traveling through a Magnet is now disposed!

The challenge is still there for you.  My "Fantastic Voyage" (no Raquel Welch dammit) through the magnet has been described.  We did not encounter a Bloch Wall or a heart valve.  So I challenge you to do the same thing.

You cannot forget that "Bloch Wall" means there is a discontinuity in the magnetic field directions inside a piece of metal or a magnet.  There is a change in the direction of a magnetic field when you pass through a Bloch wall by definition.

So I would love to see you do your own "Fantastic Voyage" through your version of a magnet.

You note that "my version" of a magnet is simple and clean.  Everybody is pointed in the same direction, end of story.  Nature usually tends to favour the simple.

With respect to your evidence for the Bloch Wall.  I have already dealt with the magnetic viewing film in another posting.  I also saw in your clip where your metal piece with the pointed end "jumps" past what you believe is the Bloch Wall.  You state that this is an indication of the presence of the Bloch Wall.  But that's not what is actually happening.  The metal piece is just jumping to a place with the lowest magnetic potential energy.  That happens to be on either side of what you are calling the Bloch Wall in your particular clip.  In other words, it's simple magnetic attraction causing the jump, not the alleged Bloch Wall.

Anyway, if you can write up the magnet fly-through I am sure we would be interested to read it.  Also, please give me any other evidence that you can offer up that you believe confirms the existence of the Bloch Wall and we can look at it and debate it.

Thanks,

MileHigh

MileHigh,

Yes different Effects entirely! But Look at EVIDENCE:

No Hurricane has ever passed across the Equator! Ever!

Water under controlled Conditions turns in Different Directions each Side of the Equator!

I have given you an Experiment that can prove that the Direction of the water turning can be changed with Magnetic Fields!

Spin is Why Iron Filings are a TERRIBLE Control and look at the Spin in the Coriolis Effect, Same with the Equator and Hurricanes Never crossing it!

This is just one more small piece to the BIG OVERALL Picture! Evidence mounts and its all got Experiment to back it up!

I am not ALWAYS Right, its not what I am saying, but when Facts are Facts, its only a fools game to deny them!

See the attached Pictures for more information:

MileHigh,

Your opinion does not make for scientific proof by any means! In-fact quite the opposite! "Nature usually tends to favour the simple." Yes it does, but your "theory" accounts for no effects in Nature, Galactic Plane? Why is there one and why not all Planets just stacked end on end like a bunch of Paper Clips hanging from a Magnet?

You're missing most all of the stuff I have provided Proof's for. Really, Why s Gravity 3% less at the Equator?

URL: https://www.youtube.com/watch?v=ZBVntSA-qoQ

The Equator has been with us through out History! Why do we have an Equator for Earth but Not for a Magnet? This is non sense! A Magnet has an Equator EXACTLY the same as the Earth does! The Equator is evident on every Planet that has a Magnetic Field! I have provided MANY Experiments and a mountain of Hard Scientific Data with references! Your too blind to see for the Trees in your Theory! Still I am not trying to convince you, I am providing some LOGIC for others reading. Some hard DATA for people to think about, real facts that can be backed up with simple experiments!

There is a MILLION Things you're missing because of your "Theory" - You have not a single bit of Scientific Evidence! You're missing Nature! Its just YOU on an Imaginary ride through your Magnet and YOU decide where your destination is!

You're Lost, really lost!

I hope you find it! I really do!

Chris:

So, are you suggesting that the equator on the earth is a sort of Bloch wall for the planet then?  I understand your points about the Coriolis effect and I do agree since this equates with what I was taught.

Interesting...I will have to think about this....

Hi Bill,

Yes of course, sure is!

Evidence speaks for itself, nonsense does too! People are not stupid! Sooner or later experiment and Logic will speak truth!

All the Best

  Chris

P.S: My devices are not dependant on the BLOCH WALL! They use standard Laws in Noise Cancellation! See: http://en.wikipedia.org/wiki/Active_noise_control

This means the take an alternate path. That's why Iron Filings are So Much Denser on the Poles that in the centre of the Magnet!

What you mean is that iron filings REFUTE your silly contention, so they should not be used!

Don't you even realize how your green film works? Clearly not. It is showing you exactly the same thing that the iron filings are showing you, because basically that is what it is. What you are calling a "Bloch Wall" is the area where the embedded ferromagnetic particles in the film are presenting a different surface to you than they are at the "poles" of the magnet. Every magnetic field modelling software, every engineer who designs things like motors and generators that work, will be in agreement with MH on this topic, and will just be laughing at you. The green film is just a convenient way of using "iron filings" and you are completely  misinterpreting what it is telling you.

The Coriolis effect has ZERO, nothing at all, to do with magnetic fields. Nothing, zip, nada. If the Earth did not rotate there would be no Coriolis effect. If the Earth's magnetic field were to flip or disappear altogether, the Coriolis effect would still happen just as it does now, as long as the Earth rotates.

Your Reason is also false. The iron filings are more dense at the "poles" of the magnet because the field is concentrated there. The iron filings are bits of material with high permeability which means, in real science-speak, that they provide an easier path for the field than does empty space or air. The iron filings trace out the field direction by their orientation, and the field strength by their concentration.

Parallel current carrying wires have magnetic field lines that are circular around the wire. This field does not "spin". If you draw out the vectors which represent these circular field lines you will see... no, scratch that, because you only see what you want to see. Anyone who really can observe, will see that the vectors describe the repulsion or attraction, depending on the current direction, just as they do in a normal magnet.

Where did you ever learn that the Coriolis effect has anything to do with magnetism? I'd like to see that reference, please.

There is no magnetic "equator" to the Earth in the same sense as the rotational equator. There is an approximate zone where the Earth's field is maximally parallel to the surface and this is what is called the "magnetic equator", equidistant from the _magnetic poles_. The magnetic poles, as you know, are not in the same location as the rotation poles of the Earth. The Coriolis effect depends on the Earth's rotation _only_, not magnetism.  The Earth's field has the same kind of orientation as the field from a sphere magnet, roughly. Near the magnetic poles, the "dip" (magnetic inclination) is such that the field points nearly up and down, which is why conventionally-mounted magnetic compasses don't work too well; they want to point down or up rather than swivelling in the horizontal plane. Near the middle of the field, that is approximately along the Earth's rotational equator, the "dip" is horizontal and magnetic compasses work the best.

Did you look a Tinman's linked clips?  They are great.

Your argument against iron filings doesn't hold water.  What do you mean by a spin?  What do you mean by an alternate path?

Look, everything related to magnetic field generation stems from one elemental thing - the magnetic field of a moving point charge.  This can easily be derived on paper using logic and mathematics.  The iron filing patterns just confirm for us visually what we know is there already from deductive reasoning.  There is no such thing as a north pole or a south pole.  There is no such thing as a Bloch Wall in a bar magnet.  There is just moving point charges and the associated magnetic fields that they produce.  Every moving point charge generates a magnetic field that undergoes vector addition with the magnetic fields generated by all the other moving point charges.  A bar magnet is nothing more than a brick of trillions of moving point charges generating a larger magnetic field.

Here are two clips that lay it all out for you:

https://www.youtube.com/watch?v=waTF7kjmmt8
https://www.youtube.com/watch?v=6xrUPxWfVvk

That's really all there is when you distill it down to it's bare essence.

You have now had several opportunities to make your case and state it on your terms.  You have been given the opportunity to discuss a fly-through of your model of a bar magnet but you have avoided that.

So what have you stated:  There is a Coriolis force because of the spinning Earth??  That has nothing to do with what we are even talking about.  You talk about being scientific.  You are supposed to discuss how a magnet works and your response is to talk about the Corillis force and how hurricanes spin in different directions in the Northern and Southern Hemispheres. Does that sound scientific to you?

Sorry but you haven't made your case at all.  Do you see that also?  There is no substance to your argument at all.

My suggestion to you is to rethink all of this stuff out in your head again and to get up the learning curve.  All of your experiments will still be the same with the same results, but hopefully you will have the proper insight.

Couple interesting photo's.
The first is a science project my 10 year old son did proving the iron filing experiment found in every textbook is incorrect. The filings align forming lines due to magnetic induction which he showed on a larger scale with short suspended iron wires. It is not a true representation of the magnetic field it is an effect produced by magnetic induction due to the presence of a magnetic field. Magnetic viewing film is simply smaller pieces of iron suspended in a film and ferrofluid even smaller iron particles. The scale of the particles may change however the effect of magnetic induction is the same.


The second picture is a bar magnets field captured using neutron spin, I believe, which is a more true representation of the field in my opinion. The reason for the curvature in my opinion is leakage, take one magnet and the field curls back on itself...the dipole field. Take two magnets together and the main field curls back plus each individual field of each magnet also curls back as flux leakage. Now take millions of dipole fields combined to produce the main field but all produce flux leakage in themselves which forms a field distortion. Obviously flux lines cannot cross because there are no lines in reality and it is a simple effect produced my magnetic induction. However the field can be distorted in the near field which is perfectly acceptable according to the laws we know.


The thing to remember is we know flux leakage occurs and we also know every magnetic field we see is the combined effort of many smaller magnetic fields. So why would we presume flux leakage occurs on one level but not the other?.

I would say: stunning, yes.  I invite any of them to show that the curl at the center that they claim exists, but which soft magnetic material does not seem influenced by does not diminish as a dipole gets longer.
