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
