Detailed Solution

Magnetic configurations do not always have to exhibit distinct north and south poles. This is because the concept of north and south poles arises from the existence of a net magnetic dipole moment. If the source of the magnetic field does not have a net magnetic dipole moment, it may not exhibit a clear north or south pole. In other words, the presence of well-defined north and south poles in a magnetic configuration is contingent on the source of the field having an intrinsic magnetic dipole moment.
