Question

Magnetic susceptibility χ is defined as:
  1. A
    B/H
  2. B
    M/H
    Correct
  3. C
    H/M
  4. D
    μrH

Correct answer

M/H

Explanation

Susceptibility χ = M/H where M is magnetisation and H is the applied field. χ > 0 for paramagnetics and ferromagnetics; χ < 0 (small) for diamagnetics.
