The Force Field Settings panel allows you to make each individual act as a force field, allowing them to affect other dynamic systems, or even, each other.

EntryWhat it does
Self EffectCauses the particle force fields to have an effect on other particles within the same system.
Effector AmountSet how many of the particles act as force fields. 0 means all of them are effectors.
