The magnetic field preferably has an induction of at least 0.08 Tesla, e.g. 0.15. The metallic bodies may be steel, iron or Ni. The particles may be modified with dimethyl benzyl ammonium chloride or chloroprene latex. The particles may be activated together with plasticizers and softening agents for elastomers. The elastomer may be styrene, nitrile or natural rubber.
