Is iron has to stick to the magnet.
lessens by distance squared
Magnets have a magnetic field about them. This field can act on objects without the magnet coming in contact with the object.
"distance"
The masses of the objects and the distance between their centers.
it is like a magnet to metal and the sun is our magnet to the planets but inertia is the thing that keeps it away from our magnet the sun The farther apart two objects are, the lower the gravitational force between them, so gravity gets weaker with distance. To be specific, it decreases by the square of the distance. So if you double the the distance, the force of gravity is 1/4 as strong. If you triple the distance, the force is 1/9 as strong, and so on.

Well I don;t know the correct terms,but I think the distance is sometimes affect cause if the magnet is small the force would be as strong as you think but if the magnet is large the magnetism would be stronger than the small magnet of pulling together.

Mass and Distance because if the object is bigger for Example the Earth then it would attract beacause its bigger than the moon. Distance because the farther away it is the less it could, attract like a magnet.
The masses of the two objects and the distance between the two objects affect the gravitational force between them.
