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
- AA, B, C Only
- B
- CA, C Only
- DB, D Only
Correct answer
C. A, C Only
Step-by-step solution
A. Align themselves along the directions of external magnetic field.
(\checkmark) 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.
(\checkmark) True - magnetic susceptibility () is small and positive for paramagnets.
D. Move from a region of strong magnetic field to weak magnetic field.
X False - they move towards stronger magnetic field (unlike diamagnets).
