The core of the Earth is mostly liquid metal churning around and rubbing against the steel-rich mantle. This causes a polar magnetic field with a north and south pole.
the gravitational pull of the moon
Earth's gravity is caused by its mass (or rather its energy). Everything that has mass will passively generate a gravitational field, even you and me! (Although we are not by far massive enough for the gravitational attraction between us to be noticeable.) It is not caused by the Earth's magnetic field, or the Earth rotation (in fact the rotation counteracts gravity in some places).
The mutual gravitational attraction between you and the earth.
The tides are primarily caused by the gravitational pull of the moon
The newton is a unit of force. Examples of forces are gravitational force, electric forces, magnetic forces, forces caused by pressure.
Gravitational force between objects is proportional to the sum of their mass and inversely proportional to the square of their distance
The tides are the result of the gravitational attraction between the water, the sun, and the moon.
