WBJEE · Physics · Magnetic Properties of Matter

For two types of magnetic materials \(A\) and \(B\), variation of \(\frac{1}{\chi}\) ( \(\chi:\) susceptibility) vs. temperature \(T\) is shown in the figure. Then
- A \(\mathrm{A}\) is diamagnetic and \(\mathrm{B}\) is paramagnetic
- B \(\mathrm{A}\) is ferromagnetic and \(\mathrm{B}\) is diamagnetic
- C A is paramagnetic and B is ferromagnetic
- D \(\mathrm{A}\) is paramagnetic and \(\mathrm{B}\) is diamagnetic
Answer & Solution
Correct Answer
(B) \(\mathrm{A}\) is ferromagnetic and \(\mathrm{B}\) is diamagnetic
Step-by-step Solution
Detailed explanation
Graph will be a straight line having +ve slope for ferromagnetic material and of 0 slope for diamagnetic material. 2)also change spelling of ferromagnetic in question from 'feromagnetic' to 'ferromagnetic' .
