Earth has no magnetic poles

Earth has no magnetic poles 

Compass works at equator so earth magnetic force at the poles must be very strong. Therefore an iron weight will be much heavier at the magnetic poles.  But the fact is iron weights the same at anywhere.  

Textbooks are wrong. Earth magnetic force is not caused by molten core but circling sunlight.

Earth Magnetic Field Mechanism

Sunlight on earth is an alternating current in the atmosphere induced by the light on the Sun.

Sunlight on earth is moving westward at 1,000 mi/hr at the equator as the earth spins.

This movement induces an east-west direction current in the atmosphere.

This current in the atmosphere induces compasses to point to the north.

This current also accelerates away from the equator to the poles to create polar lights.

The earth’s magnetic field is not from the molten iron core.

There will be no magnetic pole reverse unless the earth spins the other way.

Earth’s magnetic field is a misinterpretation of this circular electric current on earth.

Earth has this special east-west direction electric current in the atmosphere. Birds sense this current to navigate. We, too, use compasses to sense this current to navigate.
