A:
Just about the only thing that you can say in a general way is that
magnetism and gravity are similar to each other in that the attraction
between two objects gets usually stronger as the distance between them
gets smaller.
The gravitational force depends on the masses of the two objects,
getting bigger as the masses get bigger. The magnetic force is a bit
trickier: it depends on the details of what the atoms inside the
material are doing, what their charges are, how fast they are moving
etc.
