Homework Statement
My 10 year old granddaughter started her new school term last week and was presented with an electromagnet problem by her new science teacher. The class is allowed to use any non-physical method to solve this for their lesson next Wednesday. A direct link to my 'Dropbox' account show the picture she was given at school.
She needs to know:- Will the example electro-magnets repelling force of one kilogram be applied equally to each of the permanent magnets, or will the repelling force be divided by two, equating to the one kilogram electro-magnet force exerting 0.5 kilogram against each of the permanent magnets?

Only me of course; Granddad can sort anything out :!) Oh the faith of children.
