網頁2004年9月23日 · In interplanetary space at the orbit of Earth, the magnetic field (carried from the Sun by the solar wind) is much weaker, typically 0.00006 gauss, while at the orbits of the outer planets, it is 20 times weaker still. Yet even there the instruments of spacecraft such as Voyager 2 still measure it reliably. 網頁To generate a magnetic field, a planet must meet three requirements: 1) A molten, electrically conducting interior; 2) Convection in the interior and 3) A moderately rapid … kit and bear
