For two types of magnetic materials A and B , variation of 1 ( : susceptibility) vs. temperature T is shown in the figure. Then

Options

  1. AA is diamagnetic and B is paramagnetic
  2. BA is ferromagnetic and B is diamagnetic
  3. CA is paramagnetic and B is ferromagnetic
  4. DA is paramagnetic and B is diamagnetic

Correct answer

B. A is ferromagnetic and B is diamagnetic

Step-by-step solution

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' .
