The force between two magnetic fields is directly proportional to the product of their magnitudes - and inversely proportional to the square of the distance between them. As an object gets further away, the influencing field decreases because of the increased area it affects.

and the equation to find the force that acts between the two magntised objects is

Force = (q1 x q2) / r^2

well the force is 'proportional' to that equation but i cant do a symbol for that. the force is measured in Newtons (N) and the r (radius) is measured in metres.
