![]() Paper: On the Magnetism of Stars and Planets. " ~s Go the the Maximum" - from Physicsworld The Force Between Two Magnets as a Function of Distance - from Exploratorium Jupiter has a large, complex, and intense ~ that is thought to arise from electrical currents in the rapidly spinning metallic hydrogen interior.Įarth's ~ - from Georgia State University A reconnection is a dynamic process and comes and goes, although the time scale in the interstellar medium should be much longer than in a solar flare. But reconnection events should in general accelerate cosmic rays. The ~ has to be strong enough to produce X-rays. We will now derive the shape of those lines. The ~ at all these points is already so weak that the solar wind overpowers it and shifts its field lines, while its own motion-radially outward-remains unchanged. Although this is not completely understood, the leading theory of how it works is that Earth's ~ is caused by the motion of the liquid outer core. The ~ of the Earth has actually switched its direction many many times during Earth's history. The concept of field brought electricity, magnetism and light into a common framework. The concept of energy provided a unifying link for mechanical and thermal phenomena (remember our microscopic description of temperature as the motion of atoms).
