Gravity vs Electromagnetic Force
How is it that gravity wins over electro-magnetic force
when electro-magnetic force is more powerful?
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.
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
