Why gravitational field is strong on the poles of earth? It,s the question arises in the minds of every physicist i think just like is magnet have two poles same the earth have two pole.one is north pole and another one is south pole. the field lines are actual emit from north pole and move towards south pole .so the the distance between feild line is much lower at both poles so that,s why it interacts very largely on that poles so that,s why the field are stronger on both poles..
