Provided are a polishing composition, in which oxidation of magnetic particles hardly occurs, and a magnetic polishing method. The polishing composition (1) contains magnetic particles, an antioxidant for suppressing oxidation of the magnetic particles, and water. A magnetic field is applied to the polishing composition (1) to form a magnetic cluster (3) that contains the magnetic particles, and the magnetic cluster (3) is brought into contact with an object (5) to be polished, to polish the object (5) to be polished. |
