Fisher, Arthur
The Earth’s magnetic field creates a magnetic “bubble” called themagnetosphereabove the uppermost part of the atmosphere,the ionosphere layer. The magnetosphere plays a major role in protecting people. It shields and deflects damaging, high-energy,cosmic-ray radiation, which is created in sta...
