Question

I have heard that the magnetic poles of earth sometimes inexplicably reverse themselves every 70 to 150,000 years. This magnetic field sheilds us from the suns solar wind which could stip our planet of atmosphere and water as well as irradiate all living and otherwise things on earth.
During the transitional phase of pole flip I understand the earth would be exposed to the suns deadly solar wind because of the shift in the angle of the magnetic sheild to the solar wind. My question is could it be possible to build an artificial magnetic sheild on earth to protect ....say a house. Would it have to be an electro magnet or could any non electric magnet work?
What kind of strength and distance would this field have to be between us and the partical stream ?

Explanation / Answer
