Magnet A has twice the magnetic field strength of magnet B and at a certain distance pulls on magnet B with a force of 75 N. With how much force, then, does magnet B pull on magnet A?
Dont forces always occur in equal an opposite pairs? What does Newtons third law mean?
Apply the same logic to
earth and you. One has a million times the gravitational field strength as the other. On the surface, you weigh 165lbs? How much are you pulling on the Earth: ANS 165lbs.
