Separation in angular steps

Using a rotating HGMS ordered matrix in a quasi-transversal configuration, experiments have been performed to study the dependence of the captured mass m/sub s/ on the angle /spl alpha/ between the direction of the applied field H/sub 0/ and the ferromagnetic wires. The ordered dependence of m/sub s/ on /spl alpha/ registered experimentally reveals the possibility to successively separate a granular mixture by an adequate choice of the inclination angles (angular steps) without modifying the applied field H/sub 0/ or the average flow velocity v/sub a/. Relationships were derived connecting the magnetic susceptibilities of the mixture components with the inclination angle /spl alpha/ in order to accomplish such a separation in angular steps.
