I did ask my mechanic. He said two things while wringing the grease on his fingers into the creases of an already blackened red rag, "I'm no geophysicist, but this Plat fellow and the dynamo he keeps showing wouldn't power a decent blender, bolted or not, let alone magnetize the earth...Now give me a hit of whatever he's smoking or get out of my garage..."

The dynamo has to be anchored and your outer core is too hot to create a magneting field. You're theory is toast.

No, anchoring the dynamo to prevent it spinning would prevent it from producing any strong magnetic field.
It is not to hot.

Once again, all you have are baseless claims, which show you either don't understand what you are talking about, or are blatantly lying about.

BTW, you would have to be a genius to create a magnetic field with just one rotation per day.  That idea should be patentable if you could prove it.

Sure, if you were dealing with a tiny ball.
It doesn't make much sense to patent something that requires objects on the scale of a planet.

And of course, you ignore the fact that this is not a problem for RE, but is a failed general argument against a magnetic field. It works just as well for a FE.

how strong of a magnetic field are you looking for?
 - the same wacko magnitude similar to the gravity that crushes hills with a single rain fall?

• The earth does have a magnetic field and the surface magnetic pole locations precluding a buried permanent magnet.

The flow of molten iron and nickel due to convection (temperature differences) is turned into circular flows by the Coriolis effect.

Of course nobody's been down to see and measure it directly but, as near as can be ascertained from surface observations.

What causes the Earth's magnetic field?
Our planet’s magnetic field is believed to be generated deep down in the Earth’s core.

Nobody has ever taken the mythical journey to the centre of the Earth, but by studying the way shockwaves from earthquakes travel through the planet, physicists have been able to work out its likely structure.

Right at the heart of the Earth is a solid inner core, two thirds of the size of the Moon and composed primarily of iron. At a hellish 5,700°C, this iron is as hot as the Sun’s surface, but the crushing pressure caused by gravity prevents it from becoming liquid.

Surrounding this is the outer core, a 2,000 km thick layer of iron, nickel, and small quantities of other metals. Lower pressure than the inner core means the metal here is fluid.

Differences in temperature, pressure and composition within the outer core cause convection currents in the molten metal as cool, dense matter sinks whilst warm, less dense matter rises. The Coriolis force, resulting from the Earth’s spin, also causes swirling whirlpools.

This flow of liquid iron generates electric currents, which in turn produce magnetic fields. Charged metals passing through these fields go on to create electric currents of their own, and so the cycle continues. This self-sustaining loop is known as the geodynamo.

The spiralling caused by the Coriolis force means that separate magnetic fields created are roughly aligned in the same direction, their combined effect adding up to produce one vast magnetic field engulfing the planet.

Those flows look something like shown in here:

Why does the magnetic field move?
The lion's share of the protective magnetic bubble surrounding us is created by swirling molten iron in the outer core 3000 kilometres below our feet.

As the Earth rotates around its axis it creates twisted vortices of iron particles that carry a current, which in turn, generates a magnetic field.

Earth's magnetic fields are created by a combination of rotation and
convection currents in the molten outer core. (ABC: Julie Ramsden)

The unpredictable rise and fall of these turbulent underground systems causes constant changes in the magnetic field.

"Decade to decade you get variations as you might in the weather day to day in the atmosphere, Professor Moresi said.

"If one gets a little stronger, than the others it pulls the magnetic field in that direction."

Now, Mr Plat Terra, explain what is the cause of the magnetic field on your flat earth and explain why the magnetic poles wander so much.

The explanation you gathered is nothing but lame conjecture. There is no mechanics in your Globe theory to create a magnetic field. There is no separation between positive and negative with liquid iron from the inner core through the outer core. It’s just a molten mess and would short out if it was cool mercury. 

You cannot create a magnetic field with just one rotation per day. (You might be able to do it with 100 RPMs but would be useless for your theory. )
You cannot create a magnetic field unless you have a stationary component.
You cannot create a magnetic field without a separation between positive and negative.
You cannot create a magnetic field within 7,200 to 9,000 degrees Fahrenheit, and with liquid iron no matter how fast it spins. (Try it. Prove it)
You cannot prove so with any experiment. It would be ridicules to even attempt such an experiment. 

So, yes, your theory is indeed toast. Have you heard of cognitive dissonance?

You ddnt answer my question for some reason.

But also brought up another good point.
The magnetic field crested by the generators and dynamos youve ref'd earlier are made from electrons flowing caused by the moving of the windings.
So no the magnetic field is not caused by aligned iron in the core,
Its caused by The flow of the magma that rab has already pointed out.
Keep failing by providing examples that refute your own point.



So
What order of magnitude do you think our magnetic field is?

The explanation you gathered is nothing but lame conjecture. There is no mechanics in your Globe theory to create a magnetic field. There is no separation between positive and negative with liquid iron from the inner core through the outer core.

It's actually the outer core that's molten; the inner core is solid. But you're not one to let pesky things like facts get in the way of a rollicking argument.

It’s just a molten mess and would short out if it was cool mercury.

Well, if that were true, it's a good thing it's not cool mercury, then, isn't it! Our magnetic compasses wouldn't work.

You cannot create a magnetic field with just one rotation per day. (You might be able to do it with 100 RPMs but would be useless for your theory. )
You cannot create a magnetic field unless you have a stationary component.
You cannot create a magnetic field without a separation between positive and negative.
You cannot create a magnetic field within 7,200 to 9,000 degrees Fahrenheit, and with liquid iron no matter how fast it spins. (Try it. Prove it)

Says who? Do you have anything meaningful to back those statements up, or just more bluster? Given your fixation on high temperatures (which are actually irrelevant), you must be thinking that the Curie temperature of materials is relevant here. It's not.

Oh, yeah... you're the one here making the wild claims. It's up to you to show that they have merit. Good luck!!

You cannot prove so with any experiment. It would be ridicules to even attempt such an experiment. 

Well, you're right about that, but not for the reason you suspect. In science, experiments don't produce proof, they provide data which can lead to conclusions, which can be replaced when more, or better (or both), data is available.

So, yes, your theory is indeed toast. Have you heard of cognitive dissonance?

Yes. Never so much as around here, though!! "Cognitive dissonance" doesn't mean "anyone who disagrees with me is wrong!" The term is often heard on this forum by some flat-earther who's losing an argument at the moment., though

Yes, you can if the "dynamo" is big enough!

Yes, you can! All that is needed is relative motion!

You cannot create a magnetic field without a separation between positive and negative.

Yes, you can! All that is needed is a circulating current!

You cannot create a magnetic field within 7,200 to 9,000 degrees Fahrenheit, and with liquid iron no matter how fast it spins. (Try it. Prove it)

Yes, you can! Why would you suggest otherwise? The liquid iron and nickel are liquid conductors - why does the temperature matter?

You cannot prove so with any experiment. It would be ridicules to even attempt such an experiment. 

Why would we try? Where could you experiment with molten iron and nickel at 7,200 to 9,000 degrees Fahrenheit larger than the size of the moon.

Now YOU tell me where the magnetic field on you flat earth comes from and why do the magnetic poles wander the way they do?

Magnetic fields are not generated by "X Rotations a Day." They are generated by X RPMS.

The Globe Earth theory does not alow for a realistic magnetic field. So, some in the the Globe Comunity will settle and defend anything even if it's just a fantasy field.

Really?
The very easily verifiable world of electro magnetism would disagree.

Are you saying that the flow of magma cant create a mag field?

how strong a mag field are you expectibg earth to have/ need?

You realize generators what a high rpm because they want to produce a high mag field?

As pointed out to you the rotation of earth is not the source, its the internal magma.

Not according to the NOAA.
It might "flip and act erratic" over the magnetic South Pole, in 2019 at about 64.147°S 135.924°E, not even in Antarctica nor within the Antarctic circle.

The magnetic south pole is nowhere near those coordinates. The South Magnetic Pole is, but the south magnetic pole is roughly in the 'centre' (geographically) of the disk.

For what its worth, when I was near the coast of Antartica, I saw no flipping, which would be consistent with both models.

So what?
You were around Punta Arenas, Chile, at 53.164° S, 70.917° W and nowhere near South Magnetic Pole so, of course, you saw no flipping!
I'm far closer to the South Magnetic Pole here near Brisbane than you were.

Yes, it  is the source according to the Globe theory. Now people here want to change the theory because it's been exposed to be nonsense.

No theory is being changed!
The Earth's magnetic is thought to be generated in the fluid part of the outer core, mainly molten iron and nickel.
It is caused by thermal convection and the Coriolis effect caused by that vertical movement and the earth's rotation.

Now, there is a magnetic field on the earth so YOU tell us what causes that magnetic field on your flat earth.

Magnetic fields are not generated by "X Rotations a Day." They are generated by X RPMS.

There is no difference between those 2 other than the scale.
If it was generated by x rotations a day, then it would be generated by y rpms=x/1440 rpms
The issue is that that is not the valid unit or formula to use.

A simple dynamo like the one you have presented before is based upon linear velocity, as that is the force law relationship.
You can even get linear versions which have no rotation.

The Globe Earth theory does not alow for a realistic magnetic field.

You are yet to justify that at all.
So far all we have is your worthless, baseless assertion.

Magnetic fields are not generated by "X Rotations a Day." They are generated by X RPMS.

There is no difference between those 2 other than the scale.
If it was generated by x rotations a day, then it would be generated by y rpms=x/1440 rpms
The issue is that that is not the valid unit or formula to use.

A simple dynamo like the one you have presented before is based upon linear velocity, as that is the force law relationship.
You can even get linear versions which have no rotation.

A millions times overly complicated response to plata.
Haha

When navigating it’s good to have the correct compass for the World you live on, otherwise you can get lost. Which do you use? A compass for a Plane world that points horizontally to north or for a Hemispherical world that points to north through Earth with a guided surface pointer?

Sorry a bit behind the times again.

But for clarification you do not use a compass to navigate at sea.

The compass is used to hold a heading, which in tandem with measuring the speed of the vessel (dead reckoning) allowed the captain or navigator, using a quadrant to mark an arc of potential on their navigation maps/charts. There is a degree of error in there, but it is only used to measure the potential distance travelled between navigation points.

Navigation requires deriving the longitude and latitude of the vessel, mainly done through celestial navigation, midday during day light hours and anytime at night. All you need is a calendar, navigation tables showing sun positions and star charts relating to date.

From the 1700's onward nautical watches made this form of navigation extremely accurate and the calculation of longitude simple.

All the compass is required for is headings, if they point consistently and predictably, which you can observe with any good quality compass, they are doing their job.

Another observable fact that the majority of sailors did not get lost and those that did were down to human error.
