Expert Answer:

The direction of electric dipole is from negative charge to positive, while that of a magnetic dipole is that of area.
It's from the definition only. For example, magnetic dipole is IA, current times area, now only area is vector and current is scalar, so the effective quantity magnetic dipole is in the direction of area.
