Cast iron works great on induction — no special base needed

Yes, absolutely. Cast iron and induction are a perfect match. No special base required.

Induction works by creating a magnetic field that heats the pan directly. Cast iron is ferrous (contains iron), so it triggers the magnetic field just fine. Actually, it’s about the best material for induction — great heat retention, even heating once it’s up to temp.

The “special base” thing is a misunderstanding. Some cheaper stainless steel pans need a magnetic disc fused to the bottom. You don’t need that with cast iron. But there is one practical catch: if your cast iron pan has a very rough or uneven bottom (common with older, cheap lodge pans), it might not sit perfectly flat on the glass cooktop. That can cause scratching or wobbling. A quick sanding or grinding of the bottom fixes that if it bothers you. Otherwise, just slide it on and cook.

One more thing: cast iron is heavy, and induction tops are glass. Don’t drop it. And lift, don’t drag, to avoid scratches.

That pan is already ready. No special purchase needed.
