There is NO force making it move. There were forces when the Earth was formed that started it moving. Remember newton's First law. An object in motion........
It WOULD take a tremendous force to to slow the earth down to a stop and make it move in the opposite direction, but NO force is needed to keep it moving as it is.

The stuff that makes up the earth was already spinning in that direction when the earth gradually formed. Nothing stopped it so it has spun the same way ever since. It does slow down a little, and sometimes speed up a bit too. But essentially it keeps spinning because there nothing to stop it. This has nothing to do with gravity or magnetism or the core itself.
If it is true, as it appears to be, that the planets like the sun were formed out of initially slight thicknesses in an already thick soup of hot gases, then the initial direction of spin would necessarily have started out as a tiny eddy, as random as that, that happened to be the one that grew and continued and whose spin we each feel all day, especially at sunrise and sunset. Luck of the draw, it was a random thing.
Unless you're religious, of course.

Once an object is in motion, it stays in motion. It would take an outside force to stop it from spinning. So, there isn't actually any force that keeps it going around and around. However Earth started out, it got spun clockwise.

The reason that the earth continues to rotate in its' clockwise direction (as observed from the north pole) is;
The angular momentum that the mass of
the earth is conserved, and without any appreciable friction encountered
from the almost perfect vacuum of space, the entire planet with its atmo-
sphere will continue to rotate indefinately. the conservation of momentum
is the essential reason for the continued rotation of the earth.

It's already tuning clockwise. The Question is what force causes it to sloow down. Just like a spinning top, once it is spinning, air and ground friction causes it to slow down. The earth spinning continues because 1) there is a lot of mass spinning which takes a lot of force to slow it down, 2) the vacuum of space does not provide much friction to slow it down. 3) the liquid core slows it the most, (just like a spinning egg slows down when it's not boiled)

The molten core of the earth is slowing turning and it in turn makes the outer mantel turn.
