Track cogs are screw-on. IG hubs use a cog with three lugs that are held on by a sprung clip. They're not very expensive.

No worries, it's best to check the compatibility with your precise hub. The SJS product descriptions are good for that.
IGH newbie here... I've just got my hands on a wheel with a 3 speed Nexus and am looking into gearing options. I have an 18t cog from a track wheel that I want to use - can I fit it to the Nexus or do I need to get a specific cog?
