When the battery connected:
An AAAA cell has 200-350 mohms internal resistance. A 9v battery has 6 of them in series (many of them are literally that, others have their cells as a stack of plastic buckets). The nose ring is a short run of wire, it's idunno a 0.2 ohm heater?
I think the septum is going to get pretty toasty.
I just tested this (for science!) with a 9V battery and an iron nail of roughly nose-ring diameter. Both the nail and the battery get unpleasantly hot after several seconds. I don't think they'd get hot enough to burn you, though. (Don't take my word, though, please!) I believe the internal resistance of the battery does also increase with the temperature, so it effectively somewhat self regulates itself.
Common nose ring materials like Titanium and Stainless Steel are 4× and 7× more resistant than iron, which means they should dissipate more power than the nail, and thus get hotter. I was calculating something around 3 milliohms for a titanium 16 gauge 10mm wire, and 0.7 milliohms for an iron wire.
Regardless of material, at 1000 milliohms internal resistance, i think the battery itself is doing most of the heat dissipation. (But also over a much bigger surface area!)
How long did you keep the nail on the battery for?
A 9V battery can be used as a foam cutter.
Styrofoam and most art foams melt at about 200°C

Thank you for your service
Well now I want to try this with my septum piercing and find out
Do it with the piercing OUT OF YOUR BODY. You don't want a hot piece of metal that you can't get off of yourself fast enough.
You could put one in a hot dog and shock it if you want to try it without making your nose toasty
If you do please let me know what happens lol.
Wakey wakey, septum bakey
Would the person feel anything? Presumably the electricity would flow through the metal as path of least resistance?
You don't shock the person.
You heat up the metal until it burns them.
I used to burn paper with a 9 volt and a paperclip. Good times
Yes, it would heat up. It would not be pleasant
They prob wouldn't get shocked but the ring and battery will get very hot very quick as there i pretty much no resistance wich means there is a lot of current flowing.
Someone else in the comments claimed to have calculated a resistance of 0.2 ohms.
I=U÷R
9V ÷ 0.2Ω = 45A
45 amps is a lot of current to flow through a nose ring. I don't know how much that is in heat but i'd expect you to get burned from it
You won't get more than a few mA out of an alkaline, but heat does build up. (Internal resistance)
A NiMH on the other and can give over 10 amps. They're a seriously risky thing to leave around loose metal bits. Or attached to thin wires.
Definitely won’t get shocked. I’ve run estim through nipple piercings and no shocks
Just put a 9volt in your pocket with some change
No, 9v batteries have almost no shock to them. Put one on your tongue or lick your finger and touch the terminals. You’ll feel nothing.
Dry skin is hundreds of thousands of ohms. Even wet skin has pretty good resistance. When you touch a 9v to your tongue, you're starting to mess around with lower resistance flesh, it is definitely not a comfortable thing to do.
The metal ring doesn't do anything to move more electricity into your body, but it soaks every electron the battery can push and turns it into heat. Best I can figure it would amount to a few watts, which would be toasty if you were holding it between your fingers. The septum is a thin piece of flesh, I think it would sauté pretty quickly.
But it'd probably get really hot
You're doing it wrong. You gotta place a metal sphere close to it connected to a Van de Graaff generator.
