Magnets
    #6789081 - 04/14/07 10:59 PM (16 years, 10 months ago)

A couple years ago I got on a magnet kick for a while. I bought a bunch of various rare earth magnets and some fun things to play with. If you have never had any experience with rare earth magnets then you don't understand the true power of magnetism! Imagine two magnets just 1/2 inch in diameter and 1/4 inch thick that are so strong that you almost can't even pull them apart! And they stick together so powerfully that I got some nasty pinches/blood blisters by playing with them. I bought a couple larger magnets also that are borderline dangerous to play around with!!

But the magnetic levitator was by far the most interesting thing I played with. It is truly permanent magnetic levitation using no gyroscopic action or electricity. It was amazing to set it up and then sit there and and watch the magnet float freely in mid air indefinately! It uses a simple combination of one large magnet above one smaller magnet which was suspended between two pieces of a dimagnetic material (pyrolitic graphite in this case). Once you set it up and fine tuned it the smaller magnet would just float there forever completely unaided by any other means then the force of the other magnet. Fun stuff.

You can get one of these levitators here. And this site has lots of other fun magnets to buy as well.

Neodymium magnets are so much fun to play with, and they're so strong. A couple years ago I got some 1" cubes and they were so freaking strong. If I had metal in my shoes I would have no doubt that they could suspend me from the ceiling upside down. I got some little tiny ones too, they were just fun to throw at stuff and watch them stick.

I'm assuming they're ferrite magnets?

I've always been fascinated by magnets as well. I've got a bunch of old driver magnets laying around my room. They are ridiculously strong. haha

No not ferrite, neodymium ones are the really strong ones that can crush your fingers.

Hey Summit, nice to see ya again.

They should place more emphasis on the low entropy energy that magnets utilize.

Maybe its considered high entropy by the scientific community, I dunno.

Either way powerful magnets could totally be used as an energy source, particularly for transportation.  Would it be considered mechanical energy then?  Is it mechanical energy? Doubt it could be converted to electricity tho... different problem there.

I guess it would come down to weather or not there are enough magnetic metals in the earth to use for the mass production in transportation vechicles.  Then again, there is little chemistry can't do when it comes to changing physical properties...

Seguays, those things with two wheels and a platform that people stand on to drive around on sidewalks and shit, they run on a pure free energy magnet engine.  Why the hell not cars, busses, and trains.  I think there are trains in Japan that run off magnets....

So what the fuck?  Why isn't the human race investigating this stuff more intensely?:thumbdown:

Sorry man, don't wanna totally change subject or anything.... just kinda went that way.  And damnit, i wanna post in the veterans pub! :inlove:  Just a little more time...
