Well Dexter_Neo, 'magma revolving around it's core' is what gives Earth it's magnetic dipoles. It's not related to Gravity. Gravity is fundamental to mass. As I've already mentioned in my previous post it's present between any two bodies of mass.

When we speak of creating gravity it should be understood that we are speaking of artificial gravity say, for use in a space-ship. Your point is very much valid that we don't really create it but only simulate it's effect by creating some other kind of force.

Our understanding of Gravity is still very little and we are yet not sure about what causes gravity. The search for "Graviton" is still on. Some physicist claim to have clues on it. And maybe if we find 'Graviton' we will be able to manipulate gravity. (One way of creating it)
