A
(A)-(III), (B)-(I), (C)-(IV), (D)-(II)
B
(A)-(I), (B)-(III), (C)-(II), (D)-(IV)
C
(A)-(IV), (B)-(I), (C)-(III), (D)-(II)
D
(A)-(III), (B)-(IV), (C)-(I), (D)-(II)
Answer
(A)-(III), (B)-(IV), (C)-(I), (D)-(II)
Explanation
Solution
(A) The graph between magnetic susceptibility and magnetising field is as shown in (III).
(B) For x<a, the magnetic field due to a current-carrying wire is given by: B=2πa2μ0Ix, matching graph (IV).
(C) For x>a, the magnetic field due to a current-carrying wire is given by: B=2πxμ0I, matching graph (I).
(D) The magnetic field inside a solenoid varies with distance as shown in (II).
