Very nice article, I did not know about the four types of magnetism. I urge you to also research the effects of magnetic induction and the use of permanent magnets in electricity generation. I believe the permanent magnet's source of energy is the future energy source for our civilization. We have been using brute force to spin magnets inside coils to generate electricity for over a century. The next generation of energy production will take advantage of the vortex that the magnet produces in the ether. Here are a couple of videos I found that helped me.
