Gravity is a force that attracts all matter.Magnetism attracts only a few elements.

I think its gravity caused by weight.
Sir Issac Newton proposed theory of gravity. He formulated the relation between the force of gravity and the mass and the distance between the masses. This theory failed to explain as to why there is attraction between the masses and not repulsion. With every attraction you have to have corresponding repulsion. That problem is resolved with the discovery of antimatter. So like attracts like. So matter attracts matter and antimatter attracts antimatter. This fallows that matter repel antimatter. So force of gravity between the two masses of matter or two masses of antimatter is directly proportional to the product of masses or anti-masses (Antimatter). The force of repulsion will be directly proportional to the product of mass and anti-mass (Antimatter). It fallows that the force of repulsion is inversely proportional to square of distance between the two.
This question has been pondered indefinitely, mass attracts all other mass, thats a fact, but the essence of this phenomena, though exhaustively probed and tested, eludes a definitive answer, one latest viewpoint is that matter contracts space, inviting all other matter toward it.

The force of gravity; not the attraction of the Earth for all matter on it, but the same force that attracts all matter to all other matter.
You cannot. All matter attracts other matter with a force which is gravity.
I think its gravity caused by weight.
No, I don't think this is possible. The force of gravity is "universal", meaning that all matter attracts all matter.
Gravity, as it is the force which attracts the matter together.
Gravity is not unique to the Earth. All matter has gravity and all matter attracts all other matter. Since the Earth has mass it also has a gracvitational field associated with it.

According to Newton's Third Law, there is a pair of forces: Earth attracts satellite; satellite attracts Earth. It really doesn't matter which of the two forces you call the "reaction force".
Gravity, electrostatic force, and magnetic force all behave that way.
