1 If the distance between two magnets is doubled the magnetic force between them will fall to a quarter of the initial value. #(F//4)#.  If the distance between two magnets is halved the magnetic force between them will increase to four times the initial value. #(4F)#.
A: Dear Anonymous, As you point out, you can't create energy with magnets, but you can store energy. When you push two same-sign poles together it requires energy. This energy can then be released and do useful work when you let go of the magnets.: 1) You could always remove the energy for use once, just by letting two oppositely polarized magnets attract and do work as they approach each other. That's just like how you can get work out of letting some object fall in a gravitational field or from the attraction of opposite electric charges.
