We organise a rope pulling contest.
At one end of the rope we have farmer Joe and his goat. At the other end of the rope we have farmer Joe's horse. We shall assume Joe and the goat to be positive forces and the horse a negative one.
As both the goat and Joe himself are at one end of the rope Joe does-not have to compete with the horse on his own. The Goat is helping him after all.

congratulations you have now agreed with part 1

We now replicate the rope pulling contest using springs. (Physicists love springs)
We have the Joe spring the Goat spring and the Horse spring.
2 forces in our so labeled positive direction and one in the negative.
Joe and is still assisted by the goat!

congratulations you have now agreed with part 2

We now replicate the spring/rope puling contest using magnets.
The only thing we are going to change this time is that in stead of a pulling goat magnet we will have a pushing goat magnet at the other end of the rope.
The goat remains a positive force.
Nothing has changed! Joe is still assisted by the goat!
******************************************************
congratulations you have now agreed with part 3
******************************************************
We now replicate the experiment using Joe the primary rotor magnet and the Goat with Horse secondary Rotor magnet.
Joe moves towards goat and horse. Joe pulls, the horse pulls, the goat pushes.
The reader puts his hands in the air, "OMFG the goat is still helping joe."

I think it's quite the joke? hehehe
