Is gravitational energy continuous?

Quote by russ_watters View Post
The moving compass needle slows or accelerates the rotation of the earth (or makes it wobble? not certain of the direction of the force/torque). A teeny tiny little bit. That's what Dale meant by "vastly overwhelmed by the rotational KE of the earth".
It won't make it wobble if there is an even distribution of compasses or magnets.Which there probably is.
If energy is conserved when the Earth's magnetic field flips again in the other direction won't it speed up if it ever slowed down in the first instance.

it is static meaning that it does not carry gravitational energy away from the system.
Aha, that is what I needed to know!

Thanks all…
