How do I create a magnetic field

Hi,

I need to have all objects within a radius of a particular object need to get attracted to it..and move towards it.. like a big magnet.

Is there a inbuilt way to do that.

Try this:

Nice. :D

R0J0hound .. could you point me to a reference for those forumlaes.. how did you arrive at it?

The force calculation is a simplification of gravitation.

http://en.wikipedia.org/wiki/Newton%27s_law_of_universal_gravitation

So that gives the force, and the angle should be toward the magnet so I converted from polar (distance, angle) to caresian (x,y) so I could sum up the forces before applying them to the player.
