Solution

All magnets are not the same. Some are weak and some are strong.
A weak magnet is one that has less magnetic strength. A strong magnet is one that has large magnetic strength.
In magnet X, more iron fillings are accumulated at the ends, in magnet Y, it is less, and in magnet Z, it is very less. (1 mark)
Hence, we can say that magnet X is the strongest among all and its strength is also maximum.
Hence, the correct order is X > Y > Z. (1 mark)
