The Earth's magnetic field has undergone various investments throughout history: The south pole has become the north pole and vice versa. The magnetic field is due to the movement of liquid iron in the outer layer of the Earth's core and therefore to the variations of the field, including inversion. The point is that it is not easy to investigate these facts. In the laboratory they try to perform simulations and this time they have managed to invest. A group of French physicists have seen the inversion of the magnetic field produced by sodium liquid in intervals of 10-180 seconds, heating 160 liters of sodium to 110 ° C and causing turbulence.
