Gravity and Electromagnetism are the same.
Gravity is an effect, Force (weak) caused and multiplied by the mass of quarks. Electromagnetism is the same force exerted by quarks in atoms that occurs in sand (silica) earth however it is not concentrated. The density of Certain metallic atoms allows for the N/S of quarks to align and therefore create magnets. A flavour of magnetism if we can call it that. Which in turn gave us electricity. Quarks are... "The magnetic moments of the proton and the neutron derive from the intrinsic moments of their quarks and any dipole moment of the quarks within the nucleon. The magnetic moment of a proton, measured in nuclear magneton units, is +2.79285. The nuclear magneton is defined e(½ h )/(m P c) in the cgs system and e(½ h )/(m P ) in the SI system where e is the unit of electrical charge, h is the reduced Planck's constant, m P is the rest mass of a proton and c is the speed of light. It has the dimensions of energy per unit time. The magnetic moment of a ...
