Expert Answer:
A magnetic dipole
consists of two unlike poles of equal strength separated by a small distance.
The direction of magnetic moment is from South pole to North pole of the dipole.
The direction of magnetic induction :
1. At a point on the axial line of the dipole
Magnetic induction (Bs) at P due to S pole of dipole is along PS and magnetic induction 
due to N pole of dipole is along NP produced.
Since N pole is nearer to the point P, so effective magnetic induction will be along NP produced.
2. At a point on the equatorial line of the dipole
Magnetic induction (B) at P due to N pole of magnet is along NP produced and magnetic induction (B') at P due to S pole of magnet is along PS.
The resultant direction of magnetic field 
is parallel to NS i.e. along PS.
