The Gravitational Force Is Always Cumulative

Gravity is so important because unlike the other three fundamental forces, electromagnetism and the nuclear forces, gravity doesn't have. There's no such thing as far as we know as negative gravity or negative mass. So that's why on a scale of, say, planets in a solar system, gravity rules the day. And even think about how big the earth is compared to the size of the magnet and the fridge, you can see how much strong the electromagnetic force is compared togravity.
