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

The two ways are:

● Put both the metal bars in the heap of iron fillings and bring them out. The one which attracts the iron fillings will be the magnet.

● Bring another magnet towards both the metal bars. The metal bar which attracts/repel the magnet is itself a magnet.
