Hello.
Welcome!
I've been mulling over Foucault's Pendulum as there appears to be this great hang out in regards to it function during solar eclipses. Given that we know by many other means that the Earth is flat[citation needed] we therefore ought to quickly pounce on any anomalies found in science (falsely so called) experiments that are touted as proof of anything.
Good scientists never claim scientific experiments are proof. You're new here; please consider this
article on the nature of scientific proof.
What's the significance of solar eclipses?
Looking into the Pendulum's activity that supposedly explains the rotation of the earth I find an incredible insight right off:
Ring magnets are used to help pull the pendulum into a near perpetual swing.
Please elaborate.
There are various mechanisms used by some of them to counter friction and keep the pendulums in motion, but others use no assistance at all; if well designed and constructed (massive bob, long arm, low friction) [hi, markjo! I'm longer-winded than you are!] they will swing for a long time, but do stop swinging eventually.
Think on this. They are employing magnetism to move the pendulum. It's perfectly dead center of the ring magnet so the pull is neutralized by it's geometry.
Consider the factors here. Magnetism, and relative position there in the magnetic field. Most of us by now realize that the earth has a magnetic field akin to a ring magnet with north at it's center and south outfacing.
Well, no, but go on...
I propose that the angular offsetting of the swing is due to asymmetrical placement of the pendulum on the face of the earths ring magnet field.
It's hard to see why this would produce the effect we see. Perhaps a sketch illustrating what you're trying to say would be in order.
When below the equator they claim it goes in reverse
It's more than a claim... this actually happens.
At the equator it will continue to swing in the same direction. The equator I propose to be in an area of near equilibrium given it's position in the magnetic field.
I don't see why midway between the center and edge (the "equator" in FE parlance) of a disk magnet would be somehow special. Again, an illustration may help.
The earth's magnetic field has low inclination at the equator - the field lines are approximately, but not exactly, parallel to the surface there.
The green line in that image is zero inclination. Note that it's fairly close to the equator and crosses it in places, but doesn't follow it.
A way by which this all can be tested is to work with ring magnets of greater size and pendulums which could be novelty toy sized to experiment with and take behavioral observations of. If we could get an uncorrupted mathematical mind on this to drive the experiment data could be extracted and applied to develop instrumentation to at least tell us within what ring of the flat earths magnetic field we are at anywhere on earth, but also make great strides in verifying the flatness of it.
An interesting experiment would be to run tests close to the equator, at about the same distance from it on the same side, in different places, like Quito, Ecuador (20° north dip), coastal Brazil (0° inclination), and coastal Gabon (30° south dip) or Indonesia or Malaysia (20° south dip). If the pendulum precesses in opposite directions according to the magnetic inclination rather than which side of the equator, you might be on to something!
Good luck!
