magnetic separation - an overview | sciencedirect topics,magnetic separation takes advantage of the fact that magnetite is strongly magnetic (ferromagnetic), hematite is weakly magnetic (paramagnetic), and most gangue minerals are not magnetic (diamagnetic). a simple magnetic separation circuit can be seen in figure 1.2.5 .]..eriez magnetic separation,eriez is world authority in magnetic separation technologies. since 1942, eriez provides a range of permanent and electromagnetic separators for many industries. permanent magnets eriez permanent magnetic separators require no electric power. with proper.determination of eddy-current and hysteresis losses in the magnetic circuits of electric…,we consider the problem of separation of the total losses in the electric steel of a magnetic circuit into two components: the losses caused by hysteresis and the losses caused by eddy currents. the solution of this technical problem would enable us to guarantee the possibility of efficient design and construction electric machines with magnetic circuits characterized by low magnetic losses.chapter 10 faraday’s law of induction -,faraday’s law of induction 10.1 faraday’s law of induction the electric fields and magnetic fields considered up to now have been produced by stationary charges and moving charges (currents), respectively. imposing an electric field on a conductor gives rise to a.
