RIO DE JANEIRO, BRAZIL - The Earth’s magnetic field is vital to life on our planet. It is a complex and dynamic force that protects us from cosmic radiation and charged particles from the Sun.
Without this protection, the Earth would be like Mars, arid and with high temperatures. The magnetic field is largely generated by an ocean of superheated, swirling liquid iron that makes up the outer core around 3000 km below the earth's surface.
A region of reduced magnetic intensity has been detected between Africa and South America, which has attracted the attention of researchers. This anomaly . . .
