In this question, the iron, that is f .e.
00:05
As well as cobalt, nickel, these three are ferromagnetic.
00:10
Ferromagnetic in nature.
00:13
Whereas or u.
00:14
V .d .m.
00:15
I .r .p .t.
00:17
So these are diamagnetic in nature.
00:22
So we have to explain here why magnetic metals.
00:27
So here we have to explain why the magnetic metals.
00:31
They are found only among 3d as well as 4f elements.
00:38
Why? why here? cantium, titanium.
00:42
They are also 3d elements.
00:44
They are also 3d elements.
00:47
Why they are diamagnetic? so this is the question.
00:51
We have to answer it.
00:53
So whenever we see here, i .r.
00:57
So i .r.
00:58
It is a solid state...
