I always wonder whether what I as a human consider a beautiful cat, dog, panda, etc. would be considered beautiful by other cats, dogs, or pandas. I also wonder how other mammals would define attractive--is is all smell, or is it something else?

I was hoping someone here would have an idea, or lead me to a book, or something.

I am making a model of a sci-fi tank that uses anti-gravity as part of the propulsion system. I was thinking of using rare earth (NdFeB) magnets with opposite poles facing to create the anti-gravity effect.
I am also wondering if I should also use same pull strength magnets on both the model and base? Should some magnets be used as attractors to keep the model steady and from flying away on its own?
