<P> Gravitation is by far the weakest of the four interactions at the atomic scale , where electromagnetic interactions dominate . But the idea that the weakness of gravity can easily be demonstrated by suspending a pin using a simple magnet ( such as a refrigerator magnet ) is fundamentally flawed . The only reason the magnet is able to hold the pin against the gravitational pull of the entire Earth is due to its relative proximity . There is clearly a short distance of separation between magnet and pin where a breaking point is reached , and due to the large mass of Earth this distance is disappointingly small . </P>
