Magnetic Materials & Curie Law
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:
Show answer and solution
Answer: (b)
- A: true, the dipoles (and a paramagnetic rod) align along the external field.
- B: false, the attraction is weak, not strong.
- C: true, is small and positive (slightly more than zero).
- D: false, they move from weak to strong field; strong to weak is diamagnetic behaviour.
- So the answer is (b) A, C only.
