but if the field reverses, wouldn't the Earth flip over and the rotation dramatically slow down?

No.... an electro magnetic field doesn't impart any momentum so it could not affect the Earth's spin. You might have trouble getting your cell phone and Ipod to work after the shift though.

NO. The earth has been spinning in counterclockwise direction (viewed from the north rotational pole) for 4.5 billion years. The earth's magnetic field has reversed hundreds, maybe thousands, of times without affecting the direction of rotation. A reversal of magnetic field could only be detected by instruments like a compass, and would not affect anything else.

The question is posed backwards. The melted metal that makes up the center of the earth is moving and therefore causes a magnetic field. The magnetic field could not shift unless that movement also changed. The metal has to change movement before the field would. If you could impose an external magnetic field on the Earth, then the molten metal would start to go in opposite directions and then change the Earths rotation.

Magnetic field has reversed several times along the history, and the Earth has always spin in the same direction. Magnetic field has to do with magma convection, and not with the rotation of the planet.

No. Reversing the magnetic field has no effect on the Earth's rotation. And according to the available evidence, pole reversals have little effect on anything...it's not a disaster scenario in the slightest.

No, the magnetic field is a forcefield on the planet that has to do with the pole. The earth's rotation, etc has to do with gravity. It would be like dropping a vase: you drop it one direction facing down, it drops, you drop it facing the opposite direction, it sill drops. My point being that the forces making the earth spin and that of the magnetic poles are not related.

Rocks that are formed from the molten state contain indicators of the magnetic field at the time of their solidification. The study of such "magnetic fossils" indicates that the Earth's magnetic field reverses itself every million years or so (the north and south magnetic poles switch). The world has been spiining in the same direction regardless.

first the world spins the other way ,then all the ocean curents ,aircurrents and weather patterns would reverse .turning the globe into a giant washing machine ,then the magnetic out put would start again ,but why would the field reverse????.the dinamo is only turning the other way

No. Earth's magnetic field reverses approximatley every 300,000 years, yet the sun has has always and will always continue to rise in the East.

No because that's two different energies, centrifigul motion, and magnetism. However, will the earth physically flip-over to match the polarity flip?
