Question:
How is it that gravity wins over electro-magnetic force when electro-magnetic force is more powerful?

Replies:
Gravity doesn't win over electromagnetic force. The motion of two electrons is completely dominated by the EM force between them -- the gravitational force is relatively negligible. If you stack the deck against the EM force, say by measuring the force between two rocks each with one extra electron, then the gravitational force wins.

Tim Mooney

Why do you say that gravity wins? A small magnet can pick up paper clips. This means that the magnetic force applied on the paper clips by the tiny little magnet is more than the gravitational force the entire earth can muster.
