A magnet is suspended in the magnetic meridian with an untwisted wire. The upper end of wire is rotated through 180∘ to deflect the magnet by 30∘ from magnetic meridian. When this magnet is replaced by another magnet, the upper end of wire is rotated through 270∘ to deflect the magnet 30∘ from magnetic meridian. The ratio of magnetic moment of magnets is
