ABSTRACT:
A materials separator for segregating nonferromagnetic conductors from commingled nonferromagnetic materials, the separator including guide means for directing nonferromagnetic materials into a stream, and steady-state magnetic means comprising a plurality of north and south magnetic poles arranged in stripes of alternating polarity at a substantially uniform angle to the stream for establishing in the path of the stream a periodic series of oppositely directed, static magnetic fields which induce eddy-currents in the conductors.
