The compass needle aligns in the direction of the magnetic field between the bar magnets.
In the presence of the magnetic field between the bar magnets, the compass needle will align itself in the direction of the field.
The magnetic field lines around a magnet point away from the north pole and toward the south pole.
As a result, the north pole of the compass needle will be attracted to the south pole of the bar magnet and point towards it.
This is because the compass needle experiences a magnetic force due to the interaction between the magnetic field of the bar magnets and the magnetic field of the Earth.
The magnetic field lines of the bar magnets cause the compass needle to align in the direction of the field, indicating the direction of the magnetic field between the magnets.
