how to detect an open wire end in the ceiling?

How do I detect the open end of a wire in the ceiling? Previously there was an existing wire for the track light but a painter covered up the hole in the ceiling and retextured the patch so I now have no clue how to find the open end so I can install a ceiling light fixture. I still have an existing switch in the room. Please, help. Any suggestion is greatly appreciated.

If the wire is live, which it should not be unless it is in a junction box, you might find it with a proximity detector(sometimes called a cricket, etc). Available at homes/hardware stores. They emit a beep or chirp when close to a live wire. And some stud finders have wire detection, but also live wires.

I don't think it is in a junction box, I will ask the painter but I don't hope he will remember since it has been 6 months. Any way, I will try to call him and a wire detector as you suggested. Thankyou very much for your help.

It's a code violation to tuck a wire up into the box & dywall/mud over it
Any box must be accessible
UNLESS the other end of the wire was disconnected & marked as abandoned
Good way to cause a fire if the wires were not wire nutted pretty good
