n the diagram shown, when an object ‘X’ is brought near the ring shaped magnet, the magnet moves away from it. Four friends are discussing what they can say about X. Nikhil: X can be a piece of any metal. Shailaja: X can only be a piece of iron. Akash: X is definitely a magnet. Vinay: X can neither be a magnet or an iron piece. Who is correct?
