Two identical magnetic dipoles of magnetic moment 'm' are placed at a distance 'd' apart with their axes perpendicular to each other. The resultant magnetic moment of the combination is:

Two short magnets $AB$ and $CD$ are in the $X - Y$ plane and are parallel to $X$-axis and co-ordinates of their centers respectively are (0, 2) and (2, 0). Line joining the north-south poles of $CD$ is opposite to that of $AB$ and lies along the positive $X$-axis. The resultant field induction due to $AB$ and $CD$ at a point $P$ (2, 2) is $100 imes {10^{ - 7}}{\rm{\;T}}$. When the poles of the magnet $CD$ are reversed, the resultant field induction is $50 imes {10^{ - 7}}{\rm{\;T}}.$ The value of magnetic moments of $AB$ and $CD$ (in ${\rm{A}}{{\rm{m}}^2}$) are
