    Earth’s geographic poles don’t flip. But our magnetic poles have flipped countless times over the aeons.

        The reversal are estimated to take between 1000-10000 years. The complete latest reversal occured 41000 yrs ago & lasted only about 440 yrs.

        Geographic poles are not flipped because they are for the help in map. Magnetic poles changes with time and it's in North Canada right now.

        Neil, the question is how do we know the poles have flipped & if they are flipped, does this mean, the compass will point wrong directions?

        You run a magnetic field detector over rocks from near the mid-Atlantic ridge.

        Don't some birds and marine animals migrate using magnetic direction? How would it affect them?

        So otherwise than our compasses pointing south what would the effects be? Is it still lodestone?
