Question:

Match List-I with List-II.

List-I

List-II

 (A) Magnetic field

 (I) $NA^{-2}$ 

 (B) Magnetic flux

 (II) $NA^{-1} m^{-1}$ 

 (C) Magnetic permeability 

 (III) $A m^2$

 (D) Magnetic moment

 (IV) $NmA^{-1}$ 

Choose the correct answer from the options given below:

Options:

(A) - (II), (B) - (III), (C) - (I), (D) - (IV)

(A) - (IV), (B) - (II), (C) - (III), (D) - (I)

(A) - (II), (B) - (IV), (C) - (I), (D) - (III)

(A) - (III), (B) - (I), (C) - (IV), (D) - (II)

Correct Answer:

(A) - (II), (B) - (IV), (C) - (I), (D) - (III)

Explanation:

The correct answer is Option (3) → (A) - (II), (B) - (IV), (C) - (I), (D) - (III)

SI unit of $\vec{B}$ is N/mA.

$\phi=BA$              A → II
$=Tm^2$   B → IV
$=NA^{-1} m^{-1} m^2$   C → I
$=NA^{-1} m$   D → III
