Two magnets are suspended by a given wire one by one. In order to deflect the first magnet through 45°, the wire has to be twisted through 540° whereas with the second magnet, the wire requires a twist of 360° for the same deflection. Then the ratio of magnetic moments of the two magnets is
(a) 11/7
(b) 3/2
(c) 4/3
(d) 7/6
