An improved apparatus for magnetically filtering a magnetically susceptible component in a fluid with a matrix of magnetizable material which, when magnetized, provides a multiplicity of regions of high magnetic field gradient. A sequence of time-spaced impulsive magnetic fluxes are produced in an electromagnetic coil by periodically charging and discharging capacitor connected to the coil, the fluxes being concentrated across the magnetic matrix to magnetically collect the magnetically susceptible component in the regions of high field gradient therein. A static magnetic flux may also be provided in the magnetic matrix by a permanent magnet included in a magnetic circuit with the matrix.
