From Wikipedia, article on "Earth's magnetic field":
"The intensity of the field is greatest near the poles and weaker near the Equator. ... It ranges from about 25,000-65,000 nT, or 0.25-0.65 gauss. By comparison, a strong refrigerator magnet has a field of about 100 gauss."
The earths magnetic field results from deep in the earths core. Magnetic conduction from within the earths core is believed to be the cause of this.
earths magnetic field is generated by the circulation of liquid metal.
Scientists believe that it is the movements in the liquid outer core that create the magnetic field. Earth's magnetic field affects the whole planet.
About 41,000 years ago.
It's called the Dip.
Yes.
It is made by the movement of the earths core and magma field

because it has the hydro electric power to control the earths magnetic field
It is Earths' "Magnetosphere".
People use Earth's magnetic field for navigation, such as in compasses to find direction. Animals, like birds and fish, can sense Earth's magnetic field to navigate during migration or find their way in the ocean.

= An effect of the magnetic field is "Van Allen radiation belt" =
The Earth's Magnetic field.
Earth's magnetic field is strongest at the magnetic North Pole and the magnetic South Pole.
Because it is far too small to have any effect. The Earth's magnetic field is thought to be generated thousands of miles underground by moving rivers of iron.
