A bar magnet is immersed in a heap of iron filings and pulled out. The amount of iron filing clinging to the
$(a)$. North pole is almost equal to the south pole.
$(b)$. North pole is much more than the south pole.
$(c)$. North pole is much less than the south pole.
$(d)$. Magnet will be same all along its length.
It is known that both the poles of a magnet $(north\ pole\ and\ south\ pole)$ have the same magnetic strength. So, the amount of the iron filings clinging to the North pole is almost equal to the south pole, when a magnet bar is immersed in the heap of the iron filings.
So, option $(a)$ is correct.
