And how we predicted it is slow. Very fast magnetic flips are dangerous they can rip planet inside out. These can be made using technologies, and it was one of scenarios proposed by Light Followers. Slow magnetic flips (from 1 cycle through thousands of cycles) are not dangerous.
About axis, Earth is tilting it's axis all the time and this also happens very slowly, instantaneous tilting is as well dangerous, here main force responsible for this is Sun's magnetic field. All this is connected with Gravity.
I hope this will aid You Good Friend! Much happiness to You!
