Earth`s magnetic field and permanent magnets

Click For Summary
SUMMARY

The discussion centers on the interaction between Earth's magnetic field and permanent magnets, specifically addressing why the Earth's magnetic field does not significantly affect them. Participants noted that the strength of Earth's magnetic field is relatively weak compared to the magnetic forces within permanent magnets like lodestone and iron. The proximity of the north and south poles of a lodestone creates a balance that prevents conspicuous movement, such as flying through the air. Additionally, the effects of being at the magnetic poles were questioned, with no documented cases of permanent magnets behaving differently in that location.

I was always fascinated by magnets and I never understood, why Earth`s magnetic field doesn`t conspicuously affect permanent magnets. Is it too weak or what?
 
Physics news on Phys.org
A compass with a needle made of lodestone should work just as well as one with a needle made of iron. But if by ''conspicuous" you mean flying through the air, then notice that the north and south poles of a piece of lodestone are so close together compared to the scale of the Earth that there is just as much pull towards the north pole as there is a push.
 
But what if you were on the pole? The magnet should attract to the ground but I have not heard about such a case.
