Find the magnetic field due to a dipole of magnetic moment `1.2 A m^2` at a point `1m` away from it in a direction making an angle of `60^@` with the dipole-axis`.

Explanation

The magnitude of the field is
`B=mu/(4pi)M/r^(3)sqrt(1+3 cos ^(2) theta)`
`=(10^(-7)(T-m)/A)(1.2-M^(2))/(1 m^(3)) sqrt(1+3 cos ^(2) 60^@)`
`=1.6xx10^(-7) T`.
The direction of the field makes an angle `alpha` with the radial line where
`tan alpha=(tan theta)/2=sqrt3/2`
