My 7 year old child asked me today about magnetism. His question was "Does the magnet pull in the paper clip, or does the paper clip pull the magnet" . He then said to me "If i tie a rope to a tree and pull on the rope with enough force I will be dragged to the tree, so how do you know which item the paper clip or the magnet is creating the force. I am totally dumbfounded myself and I just said they are just attracted to each other and both are creating the force, but honestly have no clue how to answer this and would like to give him a correct answer.
