If you hold magnets in your hands, you can feel attraction or repulsion force.

All matters are holding electrons on their surfaces, therefore there is a strong repulsion force between all surfaces of matters.

Electric force is 10^36 stronger than magnetic force, why matters still attract each other with gravity? Because gravity is net forces between matters.

Since a charge's force has no boundary, any matter 1 and matter 2 at a distance R, all positive
charges in matter 1 will attract all negative charges in matter 2 and repel all positive charges.
All positive charges in matter 2 will attract all negative charges in matter 1 and repel all positive
charges.

Due to nature’s wonderful structure of the atoms, the net force is always an attractive force which is proportional to the product of their masses and inversely proportional to their distance squared, and we call it gravity. F=G x M1M2/R^2.

Gravity is an electrostatic force at nature’s special arrangement, similar to magnetic force is an
electrostatic force at nature’s circular arrangement
