Ответ:
False
Explanation:
False
The magnetic field of the earth can switch places, something that has happened before in the history of the earth.
Due to the nature of this phenomenon and because it is not known exactly why it happens, it is very difficult to predict when it is going to happen, but it is estimated that the last inversion of the Earth's magnetic field occurred 780,000 years ago.
