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
