A magnetic material has a small, negative magnetic susceptibility (). To which class of magnetic substances does it belong?

Answer and explanation

Correct answer: B. Diamagnetic substance

  1. Step 1: Diamagnetic materials are characterized by small negative magnetic susceptibilities () and relative permeability slightly less than 1.
  2. Step 2: They are weakly repelled by magnetic fields.
Answer
Diamagnetic substance.
Why not the others: Paramagnetic substances have small positive susceptibility; ferromagnetic substances have large positive susceptibility (); and ferrimagnets have strong positive spontaneous magnetization.
