Saba has 3 metal bars. To understand if they are magnets or not, she undertakes a small experiment and
holds the ends of the bars close to one another. The results of this experiment are plotted below.
Results:
End V (of Bar 1) End W (of Bar 2) Attracts
End V (of Bar 1) End X (of Bar 2) Repels
End V (of Bar 1) End Y (of Bar 3) Attracts
End V (of Bar 1) End Z (of Bar 3) Attracts
From the result above, conclude which bar(s) is/are magnetic? Give reason for your response.

Answer:
The bars 1 and 2 are magnets and the bar 3 is not a magnet.
Explanation:
This is because Bar 1 both attracts and repels with bar 2 and both of the sides of bar 3 is attracted by the same side of the bar 1 and to be a magnet it needs to be repeled by one of the end.

The bar 2 is magnet.
Explanation:
The image given in the question is attached below.
- A magnet has north pole and south pole. The poles of same orientation repel and poles of different orientation attract each other.
- The bar 3 attracts for both the sides whereas the bar 2 attracts and repels each other. The bar 1 has given only one end.
- Since, the bar 2 has both north pole and south pole. Thus, bar 2 is a magnet whereas bar 1 & 3 is not a magnet.
