Can you design a compass for a spherical world?

The south pole is under the North Pole. The north pole is under that.

Or its a ring magnet.

Either could provide reasonable magnetic fields that would be consistent with findings.

I didn't understand the first sentence, is there a drawing or a schema somewhere?

As ring magnet do you mean something like this?

Wouldn't the compass needle flip when going to the interior of the ring?

No, he means like the construction of a speaker magnet with one pole in the middle and another around:

I spoke simply and directly. What part confuses you? Both the south and north pole are below the North Pole.

As to your other query, you might note that at the south pole that indeed a compass does "flip" and act erratic.

I am going to design (on paper) a compass for a spherical world. I challenge anyone to use common sense to see if you can come up with a similar design.  Who’s up for it? 

Why design one? I have one like this, an old Silva TYPE 1, and it works quite well:

I've used this for decades.

It works well because the magnetic field around the Globe is roughly like this:

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.

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?

so you're doubling down on your ignorance then? Not only does a regular compass work just fine because it aligns with the magnetic field but the magnetic poles are NOT in the same place as the geographic poles.  Yet again you show only that you don't understand the subject you argue against. Thanks for the humor!

Of course the horizontal to north (regular) compass works just fine; an instrument designed for a Plane Earth. Why wouldn't it?

I cant visualize what kind of magnet that would be, but the loudspeaker magnet explained by Macarios would probably work well on a FE.

What maps do you use with your compass?

The magnetic field is balanced around the equator. Magnetic inclination grows when you go towards the poles. Your compass balanced for northern hemisphere woulnt work so well if used at the southern hemisphere.

For a compass to work on a FE model you need a north pole and a south pole and it needs to be consistent with known values for magnetic declination and inclination. It also needs an explanation for the poles slowly changing location.

It seems that tfes has earth  magnetism worked out with loudspeaker-like magnets, maybe you could look at that, although I wasnt able to find many details.

It works well because the magnetic field around the Globe is roughly like this:

And if you look at the magnetic loops, they go from "parallel" at the equator and hook into "perpendicular" at the poles.
This is what everyone else is talking about inclination/ ddcliantion.

Misleading picture. North, as in not North-East or North-West, but really, North, is always only 1 direction. The direction of the North Pole.

Incorrect! You really should learn a bit about the magnetic field on the surface of the Globe.


Read an early paper on the development of the Mariner's Compass in,

Terrestrial Magnetism and the Mariner's Compass

HUMAN inventions have generally grown by Evolution. Of perhaps no other than the Mariner's Compass can it be said that it came into existence complete in a moment. The person who first having a piece of loadstone or a magnet, so supported as to be moveable round a vertical axis, perceived it to turn into one particular direction when left to itself, and who found that the positions thus assumed were sensibly parallel when the suspended magnet is carried about to different places indoors or out-of-doors, near enough to be within sight of one another, invented the Mariner's Compass. There may have been several independent inventors; there can have been but one first inventor. The efforts of historical inquirers have hitherto proved unavailing to fix either time, place, or person for this invention, not more remarkable for its definiteness as a discovery than for its perennial utility to the human race. The directive quality of the magnet, which constitutes the essence of the mariner's compass, was not known to the Greeks and Romans; for in the writings of Homer, Theophrastus, Plato, Aristotle, Lucretius, and Pliny, we find abundant evidence of knowledge of all the other ordinary magnetic phenomena, but not a trace of any knowledge of this most marked property. It is clear that of all those writers, or of the observers and experimenters on whom they had depended for information, not one had ever supported a piece of loadstone, or of magnetized steel, in such a manner as to leave it free to turn round horizontally: or that if any one of them had ever done so, he was remarkably deficient in perceptive faculty. The earliest trace we now have of the mariner's compass in Europe is contained, according to Professor Hansteen (Inquiries Concerning the Magnetism of the Earth), in an account of the discovery of Iceland by the Norwegian historian Ara Frode, who is cited as authority for the following statement:— . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

You're just trying to look like a troll, right?

So, now we know how a compass would work on a Globe Earth if it had a magnetic attraction which the theory lacks.

Globe Earth has a magnetic field? Since when?

Hold on there John, how would you know that? And which South Pole are you referring to? The magnetic or the geographic? Big difference! The thing is that at the magnetic north and south poles, the magnetic field lines actually point up and down, rather than along the surface.  So really, if you stood on the magnetic  south pole, your compass would try to point upwards. Special compasses are manufactured that can point in the up/down angle of the magnetic fields, as well as parallel to the earth's surface.
As to your erratic claim, that’s just not true. If you had indeed been there you would know.

Here, read it from your favourite information source,  NASA ! The Self-Sustaining Dynamo in the Earth's Core: Origin of The Earth's Magnetism.

It is essentially generated from the rotation of the earth and convection currents in the liquid part of the core.

Now, may I ask the origin of a magnetic field in your flat earth theory, how does it work and how does it explain the known drift of both the North an South Magnetic Poles.

So, now we know how a compass would work on a Globe Earth if it had a magnetic attraction which the theory lacks.

Stop using your lack of knowledge as evidence for your argument.
