  This was great. Thank you. Solved a couple issues.

  It's own forces within / fractalized out pushed through its own internal latice across decay/gravity.

  A standard magnet doesn't work for 10,000 years. It weakens over time. Now with rare earth magnets I'm not sure how long they last.

  I have considered this for a long time, especially in regard to rare earth magnets. An engineer once told me that the magnets commonly known as &quot;neodymium&quot; magnets take a field much higher than they put out to magnetize them in the first place, thus they cannot demagnetize each other. (I don&apos;t know if that&apos;s true, I&apos;m just stating what I was told.)<br><br>I have seen some people propose that magnets tap into the aether or some other undetectable &quot;lake&quot; of energy. Some have proposed that we never &quot;generate&quot; electricity with generators or alternators, we simply pump the energy around using the magnets.<br><br>As for the comment about magnets losing their magnetic power over time, that seems to only be true if they are disturbed by another, moving magnetic field. I had thought to do an experiment (which I have never actually done) where one would place a vertical dowel in a board, place a donut magnet on the dowel with another one on top of it, with opposing poles keeping them apart, then stack washers on top of the upper magnet until they were almost touching. As gravity is constantly pulling down on the washers and top magnet, which could otherwise move freely on the dowel, where is the energy coming from that keeps them from meeting (again, assuming no other moving magnetic field is there to influence/demagnetize them)? How long could they stay this way? We&apos;re talking about common ceramic magnets, not neodymium magnets.<br><br>I don&apos;t pretend to know the how or why they do what they do. In some ways, I don&apos;t need to know, any more than I need to know where the electricity comes from that I use to power the lamp that I plug into the wall outlet (though I do know), in order to use it. Still, I am curious about this, and none of the explanations I&apos;ve heard/seen in physics books and presentations seem to satisfy completely the how and why.

  What if you separate a chunk of non-magnetic iron from a paperclip and then magnetize the iron in situ by melting it using an electromagnet and at the same time magnetizing it? The paperclip would move towards the magnet. So I guess the magnetization step would give part of its electric energy to the potential energy of the paperclip?

  It sounds like Lou Ferrigno is doing the narration.<br>Edit: From the way he&apos;s describing things, A magnetic field (and its Force) is a lot like an object. Especially when it comes to Repulsion. The magnetic field surrounding 2 repelling magnetics holds them apart (without &quot;using Energy&quot;) the same way the table holds up the books. The key difference being that a magnetic field can also pull something towards it. The concept is that a magnetic field is a kind of &quot;quantum object&quot; that&apos;s not made out of particles. It&apos;s made out of the field that collectively extends outward into the space around the particles (of a magnet).<br>Edit 2: Maybe its better to mention how Spin describes a State more than a dimensional movement? When he&apos;s talking about the Total Wave Function... and there&apos;s &quot;a spatial part and a spin part&quot;. The State part is dimensionless, so there&apos;s a spatial part and a state part. This seems relevant to the Pauli Exclusion principle too. Because we can now see how electrons can&apos;t share the same location and state. The Coulomb Force applies to the spatial relationship and the Magnetic Force applies to the State Space relationship.

  Each time a magnet attracts an object, it does work. And it can do that indefinitely. The examples chosen help create a pseudo solution and give the theory a thin layer of logical legitimacy.

  I also have had a problem with Maxwell and his equations.<br>But I did not fail in basic mechanic class.

  All magnets degrade over time due to quantum fluctuations causing depolarization of electron field rotation. Some like AlNiCo will noticably weaken over a year or two, others like cobalt samerium platinum alloy magnets will stay almost as strong after hundreds of years. I did find one brain breaker though. You need two flat pieces of iron or mild steel and one neodymium magnet. Take the pieces and put them on each pole then adjust so they touch each other and pull off. The two temporary magnets will hold it&apos;s field so strongly that they are extremely difficult to separate. How is it possible that two temporary magnets can stay charged and exceed the original magnet in binding force. 😮

  Sounds like time travel then, your example claims the person pulling the paper clip away AFTER it had already been drawn in.

  Actually most magnets do not last forever and lose their magnetic power over time.
