Carbon dating magnetic field changes

Over the last 150 years, the magnetic pole has crept north over 1000 kilometers.

The south and north pole are directly opposite to one another.

The North Pole is located in the middle of the Arctic Ocean. Because the water here is permanently covered with moving sea ice, it’s practically impossible to construct any type of permanent station at the true North Pole.

The liquid metal that flows in Earth’s core creates electrical currents, which in turn creates our magnetic field.

Unlike a solid fridge magnet, the liquid metal surrounding the inner core moves freely. Although geophysicists cannot measure the inner core directly, this is why there is a strong belief that the matter governing Earth’s magnetic field moves around.

Some believe we are long overdue for a pole reversal.

But there’s really no need to panic: NASA scientists say a reversal happens over hundreds or thousands of years.

This difference is called the magnetic inclination.

is the error of a compass needle including nearby metallic objects.

A compass needle rests freely in its casing so it can maneuver itself.

The Geographic North Pole differs from the Magnetic North Pole by about 500 kilometers.
