JOYCE CHEN20-1140, Pro-Chef Round Bottom Wok with Wood Handles, 14-inch

I have an induction cooktop. Can someone please tell me if a magnet will stick to the bottom of the wok?

What is the flat bottom diameter(what comes in contact with stove top)?

Can it stay level on a regular stove top? I am a bit concerned about the round bottom (as opposed to a flat bottom)

Is the cooking surface nonstick or plain carbon steel?
