levee's Alternative Map

Try this and see if it helps: http://en.wikipedia.org/wiki/Gauss%27_law_for_gravity#Bouguer_plate

Well, there you go:

the gravitational field outside the plate is perpendicular to the plate, towards it, with magnitude 2piG times the mass per unit area, independent of the distance to the plate

It figures that someone already did the work on this.

Edit: moved calculations to the thread about infinite earth specifically

I've often considered Levee's map. It even posits the Holy Land in roughly in the center of the map. The difficulty herein would be the necessary magnetic anomalies to make the map fit observations, where the "standard" map seems to match the magnetic field more easily.

I actually disagree. One of the reasons I so strongly support such a geography is that it accords more closely with existing navigational practice. For the sake of illustration, imagine that in the map I often post, the longitudinal lines mark the magnetic field. It's far from precise, but it will give you some idea of how I see magnetic fields working within such a model.

Are you proposing that the magnetic dipole is laid out essentially horizontally below the surface?

Well, it's possible, but I'm primarily interested in the observed magnetic field lines than the underlying cause.

I just can't fathom the way the magnetic field would propagate in such a manner with the commonly assumed pole arrangement. I will have to think about the positioning of the magnetic poles.

It's hard to get your head around, but there are plenty of configurations that would work. Here's a rough example I got by doing a quick search on Google images:

Yes, it would have to be set "horizontally", if you will, below the surface. Most models assume the poles are atop one another. I think there would be field problems not seen in the standard model, but it may explain some other phenomena equally well or better than the Cambridge model.

Not necessarily. Think of the field generated by a 'horseshoe' magnet or something similar. Once you break away from the spherical model, there are several possibilities.
