ignore child's collider

The MagicWand gameObject is the child of my Player gameObject. I increased the volume of the sphere collider of magicWand so it over-reaches the spherical collider of the Player. (It looks kinda like if PlayerGO was the nucleus of an atom and the collider of MagicWandGO was it's electron layer.)

The problem is, when I approach a PickUp item, it is picked up by the MagicWand's collider instead of Player's collider. Can this be fixed somehow?

This script is attached to MagicWand:

 public class MagicWand_P1_scr : MonoBehaviour {
     
     private bool _spellReady;
     public int _spellCharged;
     private bool _enemyWithinRange;
     public GameObject _spell;
     private Light _player2_light;
     
     // enum Spells{Shock, Ignite, AcidSpray};
     
     void Start () 
     {
         _spellReady = false;
         _enemyWithinRange = false;
         _player2_light = GameObject.FindWithTag ("Player_2").GetComponent<Light>();
     }
     
     // Update is called once per frame
     void Update ()
     {    
          Debug.Log("_enemyWithinRange " + _enemyWithinRange);
     }
     
     void OnTriggerEnter(Collider other)
          {
             if(other.name == "Player_2")
             {
                 _player2_light.enabled = true;
                 
                 _enemyWithinRange = true;
             }
          }    
     
     void OnTriggerExit(Collider other)
     {
         if(other.name == "Player_2")
         {
             _player2_light.enabled = false;
             
             _enemyWithinRange = false;
         }
     }
 
 }

         rigidbody.AddForce (_movement * _movementSpeed, ForceMode.Force);
