Like all magnets, Earth has a magnetic field. Earth’s magnetic field is called the magnetosphere . You can see a model of the magnetosphere in the Figure below . It is a huge region that extends outward from Earth in all directions. Earth exerts magnetic force over the entire field, but the force is strongest at the poles, where lines of force converge. For an animated model of the magnetosphere, watch this video: http://www. youtube. com/watch?v=5SXgOWYyn84 .
