It's actually not the magnetic field, which stop the atmosphere from leaking away, but the gravitational field. The reason for the atmosphere to stay is, that the earth provides a constant amount of force relative to the mass of earth. And there is less force pulling the atmosphere into space, and the atmosphere stays with most force, but if the force pulling the atmosphere into space increased, some of the atmosphere would leak, but the closer to the ground you get the stronger is the gravity, and that's why it would take A LOT of force to counter that of Earth.
