it was recorded 600,000 years ago when the Magnetic North became the South and vice versa..I have heard that flipping happens every 200,000 years in the Earth's Magnetic Core but I do not have an idea as to what consequences will this phenomena do unto us humans.

apart for the obvious problems with magnets and compasses, it might cause all sorts of problems as the magnetic forces that surround the earth protect us from many nasties from space. Might kill a few or all of us.
The average you quoted is correct, although misleading. Sometimes it might be millions of years between swaps, other times it has been as short as 20,000 years.
good question though
We can tell this by looking at the magnetic alignment in rocks when they are created. These are imprinted with the magnetic orientation forever, so we can tell pretty accurate when these flips happened.

The magnetic container has replaced. to objective to derive any implications from that's very pointless as we've not any way of verifying till it happens. it may desire to be an instantaneous exchange which i think of is the main possibly because of the fact the the sector is a function of the Earth's mass. For the sector to vanish, the Earth could could desire to have 0 mass. no you are able to are watching for whilst it extremely is going to ensue and the outcomes it could have different than the magnetic North pole would be someplace in Antarctica. it extremely is style of of scaremongering linked to the thought that the Mayans, a touch barbaric civilization, have been superman could could desire to are watching for the destiny. And why subject? you won't be able to do something approximately it. yet, I see no reason to rigidity, the exchange in magnetic fields has on no account wiped existence from the Earth till now, so why could desire to it next time?

Firstly, it occurs an average of every 200,000 years. Secondly, when it does occur, minor dipoles assume the job of the primary dipole and become temporary NS poles. FInally, the switch occurs. The interim period is interesting since solar radiation is directed to places other than the north magnetic pole. The entire process of switching takes a few tens of thousands of years.

THE GOOD THING IS PEOPLE MIGHT NOT SEE THIS BUT THE FIELD WILL ALLOW US TO THINK STRAIGHT IF THAT HAPPEN WE FLIP TOO WE START UNDERSTANDING THE SIDE OF RESPECT NATURE FORCES US TO THINK IF THIS SHOULD EVER HAPPEN WE BETTER HOPE LIFE CAN BE ON GOOD TERM WITH EARTH ..EARTH WILL ONLY GIVE WHAT IT NEED... SO IT LIKE BIRTH and DYING WE MIGHT HAVE TO LEARN ALL OVER AGAIN..

We walk with our heads.
(Honestly, the data you gave cannot be verified. Even a 10000 is equivalent to almost a creation of mankind...So, I don't beleive in 100 millions years ago, 300000 years ago etc., kind of data)
