I have always been fascinated by magnets,and the forces they are capable of.I have a few around all the time,and I was playing with a couple;a small one,and a larger one.
When placed in opposing polarities,of course they repelled,but only at a certain distance.When held closer,they attracted each other;I assume the attraction to the metal was greater than the magnetic field opposing them.
The further away they were from each other the less they attracted, up to the limit of measurable force with my crude instruments( a magnet on a string pendulum.)
Try it for yourself.
I used a 100 mm circular diameter magnet and a 10 mm circular magnet.
Could gravity work in a similar way..that is on small scales("small" is a relative term here) matter attracts,but on a larger scale,it repels?
Could a similar force help explain the galactic expansion?
Could gravity have a dual personality?
Just thinking.
