Answer:
the geomagnetic north is similar to the south pole of a magnet
Step-by-step explanation:
The terrestrial magnetic field is what makes compasses possible, used for location in space. Thanks to this invention, the great navigations could happen. The terrestrial magnetic field prevents the entry of particles with high speed coming from the Sun (solar wind). Upon reaching the Earth's magnetic field, these particles that make up the so-called solar wind are deflected because of the electrical charge they have. If they could reach the Earth's surface, they would damage and prevent communication by radio waves, TV, internet, etc.
An important statement about the Earth's magnetic make-up is that the geomagnetic north is similar to the south pole of a magnet.
The dynamo theory is the most accepted for explaining the Earth's magnetic field. According to this idea, iron and nickel in a state of fusion, at about 3,000 km of depth, move generating electric currents that cause the magnetic field.
