The present invention provides an electromagnetic suspension capable of suppressing interference with other components and devices, being mounted in a narrow space, and having a small thrust pulsation, a large thrust, and a high damping performance even for a high-frequency vibration source. An electromagnetic suspension of the present invention includes a linear motor that includes an armature and a permanent magnet portion, the armature including a winding and a magnetic body, the permanent magnet portion being disposed on an outer periphery of the armature and including a permanent magnet and a cylindrical magnetic body, and the armature and the permanent magnet portion being relatively linearly driven in the linear motor, in which a recess recessed from an outer peripheral portion of the cylindrical magnetic body and a protrusion protruding from the outer peripheral portion are disposed on the same circumference of the outer peripheral portion of the cylindrical magnetic body.
