There's a rotating magnetic field, by changing the 3 stator currents (which are physically separated by 120 degrees). The changing current in the stator causes current to move in the rotor loops (the squirrel cage loops), which causes a magnetic field in a rotor loop that attracts to the magnetic field in the stator coil that it's close to.
