European scientists have provided the most detailed, in their words, the card features a magnetic field of the Earth. Video it is available on the website of the European Space Agency.
Map allows you to track the planet’s magnetic field to a depth of 250 kilometers. In the presented video field visible abnormalities, such as the South Atlantic, which extends in the southern hemisphere between Zimbabwe and Chile.
In drawing up the map took three years. She managed to get through Swarm satellite mission. Map is important to assess the dynamics of the magnetic field and the prediction of his coup.
