Because Earth is a magnet.
because iron fillings is a good conductor of magnets , the force of magnets will tend to create a pattern line.
The most northern 'line' of latitude is really a point. 90 degrees latitude north is the north pole.
The farthest north latitude is 90° North. It is a single point, called the 'north pole'.
True meridian through a point is the line in which a plane, passing that point and the north and south poles, intersects with surface of the earth. It thus, passes through the true north and south. the direction of true meridian through a point can be established by astronomical observations.

Each magnet has a pole at its both ends called North pole and South pole.Magnetic field line originate from the North pole and converge at South pole; in a loop form.Weak magnets can be made strong by exposing it to high intensity magnetic field.

A line that runs from the north pole to the south pole is called a line of longitude.
The most northern 'line' of latitude is really a point. 90 degrees latitude north is the north pole.
A point or a line segment can be a preimage of itself because a line can be reflected or rotated.
The farthest north latitude is 90° North. It is a single point, called the 'north pole'.
due to magnetic line of force. opposite pole present in magnets.
The needle of a compass is a magnet, and the earth is also a magnet. The side of the compass marked N is attracted to the north pole of the Earth, and the side marked S is attracted to Earth's south pole. The compass will spin to line itself up with the poles it is attracted to. However, if you have other magnets nearby, the compass can spin to line itself up with those instead.
A midpoint is in the middle of the line but does not bisect it because it is just a point on that line and does not cross the line.
