Paramagnetic substances

Options

  1. AMove from a region of strong magnetic field to weak magnetic field
  2. BHas susceptibility less than zero
  3. CAttract strongly towards external magnetic field
  4. DAlign themselves along the directions of external magnetic field

Correct answer

D. Align themselves along the directions of external magnetic field

Step-by-step solution

Paramagnetic substances have a small positive magnetic susceptibility ( > 0 ) and are weakly attracted by an external magnetic field. They tend to move from a region of weak magnetic field to a region of strong magnetic field. When placed in an external magnetic field, the atomic dipoles of paramagnetic substances align themselves in the direction of the external magnetic field. Answer: Align themselves along the directions of external magnetic field
