Magnetic Pole Reversal
Transcript of Magnetic Pole Reversal
The graph displays the magnetic shields power decreasing over time We know from looking at the magnetic strength in rocks throughout time, and by testing our own magnetic strength today.
This can help us better understand the time in which pole reversal may happen.
There’s a thing called “dipole moment” it shows the decrease in our magnetic shield over time. In the graph below it shows the decrease as the switch is in it’s early stages if we’re correct on our assumptions Since we were not around for the last pole reversal, scientists can infer by rocks of different ages what the magnetic strength was at the time.
Magnetic pole reversal is where the poles switch, north is now south and south is now north.
The earths magnetic shield is important to protect us from asteroids and other things throughout space.
The poles being magnetic poles on either sides of the hemisphere.
Magnetic pole reversal lessens the strength of our magnetic shield. Big and.... ... small Member Member Member Member Member Member Member (cc) photo by theaucitron on Flickr (cc) photo by theaucitron on Flickr
