Assigning a GameObject to a prefab

First off I’m a beginner and this is my first game so please forget my noobness.

So I created a prefab that has a public variable FauxGravityAttractor where I am attaching a GameObject “Gravity” so they will interact with each other. The idea is I need the GameObect “Gravity” to attract (be the center of gravity) to my prefabs.

The original copy of the Prefab is fine, but when I drag new instances of the prefab into my scene, these loose the attractor GameObject “gravity”

So the Prefab is not holding the "gravity GameObject. Here’s the code:

using UnityEngine;
using System.Collections;

public class FauxGravityBody : MonoBehaviour {

	public FauxGravityAttractor attractor;
	private Transform myTransform;

	// Use this for initialization
	void Start () {
		rigidbody.constraints = RigidbodyConstraints.FreezeRotation;
		rigidbody.useGravity = false;
		myTransform = transform;
	
	}
	
	// Update is called once per frame
	void Update () {
		attractor.Attract(myTransform);
	
	}
}

Not sure if this is relevant, but the GameObject “Gravity” which I am trying to attach to the prefab has this code:

using UnityEngine;
using System.Collections;

public class FauxGravityAttractor : MonoBehaviour {

	public float gravity = -10;
	public void Attract(Transform body) {
		Vector3 gravityUp =(body.position - transform.position).normalized;
		Vector3 bodyUp = body.up;

		body.rigidbody.AddForce (gravityUp * gravity);

		Quaternion targetRotation = Quaternion.FromToRotation (bodyUp, gravityUp) * body.rotation;
		body.rotation = Quaternion.Slerp (body.rotation, targetRotation, 50 * Time.deltaTime);
	
	}
}

anyways I found some of these resources that have a similar issue, but I don’t really understanding much of it. THanks

Prefabs (which are reusable asset “templates” that exist independent of any particular scene) cannot hold references to instantiated game objects, which only exist in the context of a given scene hierarchy.

When you instantiate a prefab (through code, or by dragging it into a scene), that particular instance of the prefab can have a reference to other scene objects, but these are not saved by the prefab template itself. Does that make sense? but es
