-- Consider the following statements:(A) Diamagnetic substances are weakly repelled by a magnetic field.(B) For a paramagnetic material, magnetisation is always in the direction opposite to the applied field.(C) Ferromagnetic substances retain magnetisation even after the external magnetic field is removed.The correct statement(s) is/are
A
Only (A)
B
Only (B)
C
Both (A) and (B)
D
Both (A) and (C)
Explanation
Statement (A) is correct; diamagnets are repelled. Statement (B) is incorrect because paramagnetic materials align in the same direction as the field. Statement (C) is correct; this is the property of hysteresis/remanence.
