Depending on the simulation type to which you applied the force, you must adjust the effect of the force on that simulation:
After you apply a force to a hair object, you must set up its effect in the hair's property editor. See Setting Up Forces for Hair for steps on how to do this.
After you apply a force to a cloth object, you must set up its effect in the cloth's property editor. See Setting Up Forces for Cloth for steps on how to do this.
After you apply a force to a rigid body simulation environment, you can set up its effect on each rigid body object in its Force Controller property editor. See Applying Forces to Rigid Bodies.
For information on how to apply forces to ICE particles, see ICE Forces.
