Solution

Neutral Point
As answered previously by one of our experts...
All magnetic materials experience a force due to earth's magnetic field. Neutral points or null points around a bar magnet are those points at which earth's magnetic field get cancels out by the magnetic field of bar magnet.

We can be certain of the magnetic polarity of current carrying loop by looking at the direction of magnetic field. The magnetic field always originates from north pole and ends at the south pole, the same is applicable for all shaped wire.
