Can you design a compass for a spherical world?

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? 

I don't have a CAD program, but will do the best I can.

I will start now.

A compass’s needle aligns with the magnetic field. Not the most complicated idea.

But you're fine with a flat earth that has no southern magnetic pole?

Before you design your compass can explain how in your pic of the north pole projection with the 4 orientations, why in North America EAST the same straight line direction as SOUTH in Africa and WEST in China.

Also, where is the magnetic south pole?  Or does the flat earth have magnetic north mono-pole?

I'm working on mine. Any takers?

I'm working on mine. Any takers?

We all already have ours. What's taking you so long?

Cool!

What do you expect it to show? That south isn't in the opposite direction as north?

Any takers?

Seconded.

He gave you the clue in his challenge:

"On paper".

The one in my phone is working fine.

While you are at it, you could also explain to us how gyrocompass works on FE.

I see Plat is again proving he doesn't understand the subject. Anybody got some popcorn for his show?

I have yet to find a regular compass that works at a postion of 90 degrees to North. I bet many sea captians where crying "LOST" on the Globe seas.

What do you mean by "position 90 degrees to North??


Crazy we don't hear about sea captains crying "LOST" all the time!

90 degrees from the north pole is the equator. Why wouldn't a compass work on the equator?

I've never heard of every captain pre-GPS getting lost all the time.

Fun fact: Since when it comes to magnetic poles, opposites attract and likes repel, the north pole of a magnetic compass needle actually points toward the south pole. 

Are you literally saying that every army, all boy scouts brownies forest ranger, any 1700-1900 dutch british spanish porteguese traders, airplane (before gps) wwii bombers pilots all dont know where theyre going?

Youre arguing very easily verifiable recent and most of recorded history here?

That's right, we don't, because the Captians of old used a compass designed for a Plane Earth. The compass they used only worked on a horizontal plane to north. If Earth were a sphere they would get lost and cry for help!

Of course they knew where they were going by a compass that only worked on a horizontal plane to north. It worked great even though they incorrectly thought earth was a sphere.

Did you ever heard of magnetic inclination? Of course not.

The inclination of a compass needs to be adjusted to latitude otherwise the compass will lose accuracy.

The question is why on earth would compass inclination need to be adjusted on a FE?

Why does a compass lose accuracy if the inclination is not adjusted to latitude? Whats the FE answer for that?

So compasses (compasses) suddenly decided to not work anymore?

Heres a picture of a basket ball.

There are black lines.
Are you saying you dont understand how these various lines all around the east-west can go from south pole to north pole?

I found these memes for you Platt, since you seem to understand memes better:

Zero inclination at the equator: Balanced compass works best:


Magnetic inclination (magnetic dip):

Yet again proving you don't understand the subject. Compasses align with the magnetic field. This was pointed out to you before. That you chose to remain ignorant just makes everyone think you're a troll.

How's you paper compass design coming along?

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.
