Earth's magnetic field is relatively weak compared to the magnetic forces of permanent magnets, which is why it does not significantly affect them. The close proximity of the north and south poles of a lodestone results in balanced forces that prevent noticeable movement. While compasses made of lodestone and iron function similarly, the Earth's magnetic field does not cause them to fly through the air. At the poles, the expected attraction of a magnet to the ground is not commonly reported. Overall, the interaction between Earth's magnetic field and permanent magnets is subtle and often overlooked.
