Paramagnetic substances: A. align themselves along the directions of external magnetic field. B. attract strongly towards external magnetic field. C. has susceptibility little more than zero. D. move from a region of strong magnetic field to weak magnetic field. Choose the most appropriate answer from the options given below:

Options

  1. AA, B, C Only
  2. BA , B , C , D
  3. CA, C Only
  4. DB, D Only

Correct answer

C. A, C Only

Step-by-step solution

A. Align themselves along the directions of external magnetic field. ( ) True - paramagnetic materials have unpaired electrons and tend to align with the field. B. Attract strongly towards external magnetic field. X False - they are only weakly attracted (ferromagnets are strongly attracted). C. Has susceptibility little more than zero. ( ) True - magnetic susceptibility ( (X )) is small and positive for paramagnets. D. Move from a region of strong magnetic field to weak magnetic field. X False - they move towards
