I have heard of it for quite some time, I believe an explanation doesn't exists. But what can be the explanation. Any guesses?
Can it be explained without invoking Quantum or other such higher Physics?
What can be its implication (I guess earth also spins hence earth interchanges its magnetic poles because of this phenomena. I'm not sure I'm just wild guessing)
How can we benefit out of it. That is can we build something interesting or profitable out of this phenomena.
