Graph between magnetizing intensity and distance

Question

I just know $H = B/ \mu $
From this how can we select the graph.

Answer 1

We can think this analysing the graph,

H represent magnetizing field. So on right side where the solenoid has magnetizing substance would require less magnetizing field .

why ? That's because $\mu $ would be more.

And as from the equation given by you $H=B/\mu $
H should be less for right side.

And it should be more on left side. This can be seen as intercepts of y axis in graph 2 only.
