RayCast is not triggering another object

I’m attempting to send a ray from a little box, Object A, to another object that has a trigger collider. That other object, Object B, has a script that is basically “OnTriggerEnter” with a debug notification. I know the ray is hitting object B because it tells me it’s distance from the object and the layermask can only hit that one object.

I’ve eliminated so many variables that I really don’t know what I could have done wrong. Any help would be greatly appreciated.

Object A

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Object_Physics : MonoBehaviour
{
    // Start is called before the first frame update
    
    public int maxDistance = 50;
	//The maximum distance at which the object can be detected
	
	public double rayDistanceObj = 0;
	//tracks the distance between both objects

    void FixedUpdate()
    {
		
        
        int layerMask = 1 << 9;
		//Detects only the Mask I choose
 
        RaycastHit hit;
		
		if (Physics.Raycast(transform.position, transform.TransformDirection(Vector3.forward), out hit, maxDistance, layerMask, QueryTriggerInteraction.Collide)){
			
			rayDistanceObj = hit.distance;
		}

		
	}
		
	
}

`
Object B

using System.Collections.Generic;
using UnityEngine;

public class SC_RigidbodyMagnet : MonoBehaviour
{
   

    void FixedUpdate()
    {
		
	
		
    }
	void OnTriggerEnter(Collider other)
    {
			
		Debug.Log("Object triggered");
		
    }

    void OnTriggerExit(Collider other)
    {
		
    }
    
}

If i understand your question correctly then you assume that a Raycast triggers the OnTriggerEnter callback. This is just not the case. OnTriggerEnter is only called when an actual collision between 2 colliders takes place.

What you want to do is basically modify your code so that:

if(hit.distance < someThreshold)
{
       if(hit.transform.CompareTag("someTagOfB"))
               hit.Transform.GetComponent<SC_RigidbodyMagnet>().callTrigger();
}     

and give your SC_RigidbodyMagnet script a function called

   public void callTrigger()
