NEET PHYSICSEasy

Match List-I with List-II.

List-I (Material) (A) Diamagnetic (B) Ferromagnetic (C) Paramagnetic (D) Non-magnetic

List-II (Susceptibility $\chi$ ) (I) $\chi = 0$ (II) $0 > \chi \ge -1$ (III) $\chi \gg 1$ (IV) $0 < \chi < \epsilon$ (a small positive number)

Choose the correct answer from the options given below:

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

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

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

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

Diamagnetic Materials (A): These substances are weakly repelled by magnetic fields. Their magnetic susceptibility ( $\chi$ ) is small and negative. This matches with (II) $0 > \chi \ge -1$ .
Ferromagnetic Materials (B): These substances are strongly attracted by magnetic fields. Their susceptibility is positive and very large. This matches with (III) $\chi \gg 1$ .
Paramagnetic Materials (C): These substances are weakly attracted by magnetic fields. Their susceptibility is positive but small. This matches with (IV) $0 < \chi < \epsilon$ .
Non-magnetic Materials (D): These materials do not interact with magnetic fields, meaning their susceptibility is zero. This matches with (I) $\chi = 0$ .

Conclusion: The correct matching sequence is A-II, B-III, C-IV, D-I.
