It seems the Foucault Pendulum experiment hasn't been changed much after it was firstly introduced in 1851 as a simple proof of Earth's self-rotation.
So, I was pondering whether modern science could do something to perfect this beautiful experiment. As many Museum has electromagnetic incorporated to keep the bob swinging, I'm considering why not just let the bob statically float above that magnetic base instead of swinging around? Magnetic Levitation is a way to realize it.
The idea is pretty simple: The bob floating above the magnetic base rotating with Earth could have a relative movement with the Earth, also proving the self-rotation of Earth.
Many videos about this experiment could be found on youtube, for example, https://www.youtube.com/watch?v=g4lW7xydnH8
But I also have a concern: Would the rotating magnetic field (produced from levitation base) affect the suspended object above it if that magnetic field is inhomogeneous, which could produce force by cutting through the inhomogeneous magnetic force lines?
Actually, this idea turned out to be imperfect by an experiment I did recently. The object floating on the top of the base could be easily affected by the magnetic field, which is either controlled by alternating current (if it's electric set) or the movement of the earth itself. In another word, I can't obtain a completely static magnetic field and the dynamic field would influence the levitated object.
Not sure about this magnetic question, but there must be data about magnetics of the earth in relationslhip to equator and north and south movement of energy fields.
Yes in the future to come levitation will prove self rotation of the earth surely.
With levitation, you will have to change the magnetic poles relative to the geographical part of the earth you find yourself. If the world was not rotational gravity would be stable and accurate but its not. That is why leviational tools alike cost a lot because, it will take a lot to levitate.
If gravity was stable and the earth was not rotational, levitating cars would have been introduced and used globally but gravity of earth differs from onr point to another.
So yes someday when levitation is introduced and used it will prove earth’s rotation
