Abstract: The present invention provides a magnetic sorting microfluidic chip, including a substrate, a chip model material layer, a micro-channel unit and a magnetic sorting unit, where the chip model material layer is disposed on the substrate, and the micro-channel unit and the magnetic sorting unit are both disposed in the chip model material layer; the micro-channel unit includes a sorting channel and magnetic pole channels; the sorting channel is provided with a plurality of sorting channel inlets and a plurality of sorting channel outlets; and the magnetic sorting unit includes permanent magnets, high-permeability alloys, and magnetic pole arrays disposed in the magnetic pole channels, where the high-permeability alloys are configured to conduct magnetic fields of the permanent magnets to the magnetic pole arrays, so that the magnetic pole arrays generate magnetic fields having opposite polarities on left and right positions of the sorting channel.
