Magnetism and Matter

Match List - I with List - II. Choose the correct answer from the options given below:

1. (A)-(III), (B)-(IV), (C)-(II), (D)-(I)
2. (A)-(III), (B)-(II), (C)-(I), (D)-(IV)
3. (A)-(III), (B)-(IV), (C)-(I), (D)-(II)
4. (A)-(I), (B)-(II), (C)-(III), (D)-(IV)

Answer

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

Solution

(A) Magnetic induction B: CGS unit gauss ⇒ (III)

(B) Magnetic intensity H=nI ⇒ A m-1 ⇒ (IV)

(C) Magnetic flux =BA ⇒ weber ⇒ (II)

(D) Magnetic moment M=NIA ⇒ A m2 ⇒ (I)

∴ A-III, B-IV, C-II, D-I

Answer: (1)
