Earth’s magnetic field has a dent, and NASA is watching closely
6 days ago · Earth’s magnetic field is like an invisible shield that surrounds our planet, generated by the movement of molten metal in Earth’s outer core. This movement creates electric currents, which in turn produce a magnetic field. The field has two main poles – north and south – just like a magnet, and it stretches far into space.
