magnet B will pull half the force of magnet A. so if A is pulling 50N B will pull what force? easy.

This question is set up to confuse you by getting you to think about magnetism, when the answer can be found using Newton's Laws.According to Newton's 3rd Law, for every action [force] there is an equal reaction [also a force]. The magnetic force of A on B must, therefore, be equal to the magnetic force of B on A.
