  1. Magnetic separation

  2. Principle of magnetic separation Utilized feature: magnetic susceptibility

  3. In vacuum: B0 = 0 H 0 – magnetic permeability of vacuum (410–7 V·s/(A·m) = H/m H - magnetic field intensity (A/m) B0 - magnetic induction in vacuum (V·s/m2 = T) In any medium (e.g. particle): B =  H B = 0(H + M) = B0 + 0M particle input vacuum imput

  4. Vector of magnetic induction B in a particle is difefrent from that of in vacuum. Therefore:  = (B – B0)/B0 = ( – 0)/ 0 = 0M/B0  is the volumetric dimensionless magnetic susceptibility MATERIALS + -  paramagnetics diamagnetics

  5. Ways of expressing magnetic susceptibility  w= / M = w M volume (dimensionless) mass (specific) (cm3/g) molar (cm3/mol) generally:
