Inductor wrapping

Hi I have this inductor which is short. I removed the wire from the core. Can I just wrap the copper with insulation tape and coil it back. Will that work? Picture attached.

As long as the windings are insulated, it doesn't matter how but the insulating tape (or whatever you use) will have to be really thin and you'll have to wind tightly or the wire will have to be extended. Is insulated wire unavailable where you are?

What are the numbers on the cores?

Attaching the core picture. I dont have insulated wire here. What gauge wire? Can I use another inductor from broken amp instead?

That looks like it's a sendust core. That's unexpected. Most seem to use the cheapest cores possible.

You can re-use wire but if it has a binder on it, it's going to be a mess. You can order the wire. Bear in mind that there are different types of insulation. Most people use solder strippable because it's easier. I prefer to use high-temp insulation (rated for 200C). The insulation has to be scraped off but it's typically more durable.

Measure it with a dial caliper. It's available in 1/2g sizes so you need to get an accurate measurement.
