Question

Match column I with column II (showing electron spins in a magnetic domain in absence of magnetic field) and make the appropriate choice.

Column I	Column II
(A)	Ferromagnetic	(i)
(B)	Ferrimagnetic	(ii)
(C)	Antiferromagnetic	(iii)
(D)	Diamagnetic	(iv)
(E)	Paramagnetic	(v)

• A. (A)$\to$(iii), (B)$\to$(i), (C)$\to$(ii), (D)$\to$(iv), (E)$\to$(v)
• B. (A)$\to$(i), (B)$\to$(ii), (C)$\to$(iii), (D)$\to$(iv), (E)$\to$(v)
• C. (A)$\to$(iv), (B)$\to$(i), (C)$\to$(iii), (D)$\to$(ii), (E)$\to$(v)
• D. (A)$\to$(v), (B)$\to$(iv), (C)$\to$(iii), (D)$\to$(ii), (E)$\to$(i)

Answer 1

The correct option is A (A)$\to$(iii), (B)$\to$(i), (C)$\to$(ii), (D)$\to$(iv), (E)$\to$(v)

(A). For ferromagnetic substance, in presence of an applied field, domains get aligned with the applied magnetic field. The combined effect of the atomic magnetic moments results in a relatively large magnetization. These ordered domains persist even after removing the external magnetic field.

(B). Ferrimagnetism arises due to the unequal magnetic moments in opposite direction, resulting net magnetic moment in one direction.
Magnetic moments of the domains are aligned in parallel and anti-parallel directions in unequal numbers

(C). Antiferromagnetic substances possess unpaired electrons but they do not possess net magnetic moment due to presence of equal and opposite magnetic moments. Domain structure is similar to ferromagnetic substances but they being oppositely oriented, cancel out each other.

(D). Diamagnetic materials are those in which the electron motions are such that they produce net zero magnetic moment in absence of any magnetic field. Diamagnetic substances do not have any unpaired electrons.

(E). Paramagnetic materials are those in which the electron motions are random and they do have magnetic moment in absence of any magnetic field.

Here
$A\to \left(iii\right)$
$B\to \left(i\right)$
$C\to \left(ii\right)$
$D\to \left(iv\right)$
$E\to \left(v\right)$

So, option (A) is correct
