Magnets and Magnetism

WE all know that water falls, or at least runs downhill. We all know how to use a simple gyroscopic toy and that it will do some pretty weird things when spinning.We know about levers.Archimedes said it.
“Give me a lever long enough and a fulcrum on which to place it, and I shall move the world.”
We all think we know how electric works,or at least we’re pretty sure we do. We know about the space shuttle and we all know about the planets and gravity.
And we all think we know about magnets to. Most refrigerators have a half dozen or more holding things up until kingdom comes.
OK! So water falls from a higher to a lower place, as long as the water lasts that is. And we’ve learned how to use that fact to create billion and billions of watts of energy. We use that to create electric, by using the the emf effects we think we understand We use artificial and permanent magnets to do that. Mathematically we can figure out how to do that following the rules of conservation to make it work. WE know how to put fuel in our tanks and that when the gauge reads empty it’s time to get more. Even the space shuttle has a fuel tank. In fact, several. And when the tank is empty everything stops.
And! Oh ya! How about solar power. I love that one! Make the panel, put it in the sun, and you’ve got mail! Unless the clouds come out! Then what? OK! Wind power, unless no wind.
Every one has finite use and finite abilities. ATOMIC! You live with it. The efficiency is crappy and the waste products not nice to live with.
And all the time that simple little magnet just keeps hanging there. Every machine ever conceived of or built by man has one major stumbling block. They need a power source to work. Some sources are more finite and some more replaceable or renewable. Every machine requires power to work, or they stop working. Not the magnet! What is the magic of the magnet?
Oh sure. WE all know about them. Don’t we? One end is positive and the other negative. Lines of force called flux surround them. Push like kind ends together and they repel. And opposites attract. All the time, every time. And they just keep doing it with no end in sight. But why?
Twenty years ago they were simple steel or iron. Now some are so sophisticated that its a secret what they are made from. But they’re smaller and stronger, and permeate our lives in ways no one even dreamed of just a decade ago. Forget the ones on the frig for now. The newer ones have created smaller and stronger motors that use less energy to do more work. And the things we do with them. WE look inside ourselves and see what was only sci a few years ago. Super conductors with magnetic properties as yet still not completely understood. Oh sure. We’ve learned how to put them to use. But where does the energy come from?
Oh? By the way. That little magnet on your frig? The frig will fall apart, you’ll move more than once, and you’ll probably die, before that little magnet will stop working.
