Psuedo-science jibberish
Gravity follows the inverse-square law. That means that the gravitational attraction between any two objects diminishs sharply as distance increases. An object, even an extremely large one, 9 times as far as Pluto would have very little impact on the Earth. Jupiter is many times closer than your mythical planet
As a matter of fact, magnetic fields also follow the inverse-square law. You need to take some actual science course to learn that what you posted is pure rubbish.
It sounds like a poor rehash of the planetary convergence nonsense that was in vogue a couple years ago. The same arguments that proved convergence was nonsense also apply to what you published, so you might want to read this article to see just how wrong you are.
