Magnetic susceptibility is given by __________ (where M is magnetization, B is magnetic induction and H is magnetic field strength).

Question and options

Magnetic susceptibility is given by __________ (where M is magnetization, B is magnetic induction and H is magnetic field strength).
  1. M/BM/B
  2. M/HM/H
  3. H/MH/M
  4. B/HB/H

Answer and explanation

Correct answer: B - \(M/H\)
Magnetic susceptibility is defined as χ=M/H\chi = M/H, the magnetization produced per unit magnetizing field strength. The ratio B/HB/H is the permeability, not the susceptibility, and M/BM/B and H/MH/M are not standard quantities.
