          You are provided with two identical metal bars. One out of two is a magnet. Suggest two ways to identify the magnet.

Answer:

There are following ways to identify the magnet:

(i) By suspending the metal bars with a thread: Keep it horizontal and let it stop in any direction. If we move it by pushing it slowly and if it returns to the same direction, it means, it is a magnet otherwise it is a simple iron bar.

(ii) By attracting iron filings: If iron filings are attracted at poles, then it is magnet otherwise it is a simple iron bar.
