The invention discloses an embedded electromagnetic multi-vertical-ring high-gradient magnetic separator. The magnetic separator comprises a rack, at least two separation vertical rings, a hollow mainshaft, a controller, a sliding ring set, an electric brush set, an angle position coded disc, an angle position sensor, a magnet exciting coil, magnetism gathering medium boxes, a washing water pipe,a concentrate hopper, an ore feeding pipe, a pulsation mechanism, a tailing pipe, a tailing channel, a feeding hopper, a feeding pipe, a separation vertical ring driving system, a pulsation driving system and a controller. The at least two sorting vertical rings are vertically arranged on the hollow main shaft in parallel through spoke plates. Each sorting vertical ring is provided with at leasttwo magnet exciting coils. The magnetism gathering medium boxes are embedded into the magnet exciting coils and fixed on the spoke plates. According to the invention, high-gradient magnetic field space limitation of a centralized electromagnetic high-gradient magnetic separator in the prior art is effectively broken through; the magnetic field utilization efficiency is improved; the separation efficiency is improved; and the energy consumption is reduced.
