According to the science journal Nature, the magnetic North Pole is rushing away from Canada, towards Siberia.. This means the navigational* models based on where the magnetic poles are — that we all use to know where we are and where we are going — are becoming dangerously inaccurate. A geomagnetic reversal is a change in a planet's magnetic field such that the positions of magnetic north and magnetic south are interchanged..
Curious Kids: why do we not use the magnetic energy the Earth provides to create electricity?

The Earth's field has alternated between periods of normal polarity, when the direction of the field was the same as the present, and reverse polarity, when the field was the opposite.These periods are called chrons.
You will be quizzed on the purpose of the geomagnetic field, the meaning of the word 'repel' and solar radiation.

Earth’s magnetic North Pole isn’t behaving how scientists expected.

It produces a magnetic field in which the field lines are most concentrated at the poles. Above the surface, this field resembles a dipole with distances of several radii of the Earth (R E).On the sun's side of Earth, the magnetosphere generally extends out to a distance of approximately 10 Earth-radii, while the magnetotail extends several hundred radii in the opposite direction. Earth's magnetic field has a strength of about 6×10-5 tesla at the poles [1]. It's interesting to note that the strength of Earth's magnetic field is very weak—about 100–1000 times weaker than that of a typical bar or fridge magnet.

The Earth’s magnetism.

We measure the strength of magnetic fields in units called gauss and tesla (the modern SI unit, named for electricity pioneer Nikola Tesla, 1856–1943).

Earth's magnetic field is also known as the magnetosphere.
