1. Magnetic separation

2. Principle of magnetic separation Utilized feature: magnetic susceptibility

3. B 0 =  0 H  0 – magnetic permeability of vacuum (4  10 –7 V·s/(A·m) = H/m In vacuum: H - magnetic field intensity (A/m) B 0 - magnetic induction in vacuum (V·s/m 2 = T) In any medium (e.g. particle): B =  H B =  0 (H + M) = B 0 +  0 M vacuum imput particle input

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

5. Ways of expressing magnetic susceptibility volume (dimensionless)  mass (specific) (cm 3 /g)  w =  /  molar (cm 3 /mol)  M =  w M generally:
