Identify the incorrect statement from the following.
- A The susceptibility of a diamagnetic material is a positive quantity.
- B Paramagnetic materials obey Curie's law.
- C Ferromagnetic materials have permanent magnetic domains.
- D In soft ferromagnetic material, the magnetisation disappear on removal of the external field.
Answer & Solution
Correct Answer
(A) The susceptibility of a diamagnetic material is a positive quantity.
Step-by-step Solution
Detailed explanation
Susceptibility of a diamagnetic material is a negative quantity, \((\chi 0)\), hence it is incorrect statement. Paramagnetic materials obey Curie's law. Ferromagnetic materials have permanent magnetic domains and each domain contains near about \(10^{17}\) atoms. Magnetisation…
