Match List-I with List-II:
List-I: (A) Magnetic induction (B) Magnetic intensity (C) Magnetic flux (D) Magnetic moment
List-II: (I) Ampere meter² (II) Weber (III) Gauss (IV) Ampere/meter
Choose the correct answer from the options given below:
  1. (A)(A)-(III), (B)-(IV), (C)-(I), (D)-(II)
  2. (B)(A)-(III), (B)-(IV), (C)-(II), (D)-(I)✓ Correct
  3. (C)(A)-(I), (B)-(II), (C)-(III), (D)-(IV)
  4. (D)(A)-(III), (B)-(II), (C)-(I), (D)-(IV)

Answer: (B)

Solution

The units of these quantities follow directly from their defining relations.

Magnetic induction is measured in gauss (the CGS unit) — (III).

Magnetic intensity , from , has units ampere/meter — (IV).

Magnetic flux has units of weber — (II).

Magnetic moment, from , has units ampere·meter² — (I).

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