Question

The magnets X, Y and Z were dipped one by one in a heap of iron fillings. The figure below shows the amount of the iron fillings stuck to them.

Answer 1

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, its very less. 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.
