Magnetic Perpetual Motion Machines

Guest · Post by **Guest** » Thu May 18, 2006 7:56 pm

So what's the deal, anyone know why magnets can't propel objects perpetualy? I have an idea for one but I need to know why it's not working for other people.

I don't know much about this topic but my guess would be that natural magnets aren't powerful enough and electromagnets would require more energy than they produce.

Because energy is always lost to friction and heat.

Ok, well what about this?

If you hung a magnet by a string, then put another magnet underneath it, wouldn't the magnet on the string move around a bit? There's very little friction...

There would be a small amount of friction with the air.

Enough to stop it from moving? What about putting it in one of those sealed chambers with no air in it? I've seen one before I just don't remember the name of it.

like, a vacuum?

Yes like a vacuum, thanks.

while there is nothing logically impossible about perpetual motion, a perpetual motion machine is understood to be a device which actually yields energy while remaining in perpetual motion.

As far as we understand, nature does not allow this.

Even if u had a wheel spinning in space forever, once u started to harness that energy it would cause the wheel to slow down unless u had a 3rd party source of energy feeding the wheel.

Yeah that's where I figure magnatism and gravity might be able to work together... I wonder what causes the loss of friction.. Cause magnets do actualy provide a form of propulsion but it's hard to harness I figure...

That's the problem dick head. ANY friction is the problem.

Only one pm machine exists and it consist of the entire fucking universe.

WE aren't sure of that yet...

krakus i'm not sure what you're getting at here - what use would a perpetual motion system be?

and from what i understand, each atom exhibits perpetual motion in the form of electrons moving around the nucleus without loss of energy.

That's cool, hadn't really thought of that.

I dunno, I was looking up some stuff online and there was a bunch of machines that don't work but that look interesting enough that it made me wonder. Then I thought of the simple concept of a thread with a magnet attatched to the end and another magnet below it to move it. Simply put, if it could be moved around perpetualy, then why not?

Gravity would pull the magnet down but the magnet below pushes it up, I figure it'd turn for a little while and probably stop and hover off to the side eventualy. But only because it'd be a consistent circular orbit around the bottom magnet. Now if you introduce a magnet on one of the sides you would get a different orbit around the bottom magnet causing a shift but the orbit would invariably miss the second magnet off to the side and I figure there might be a way to compensate for it by using a third/forth/fith magnet. Not sure on how many but it would depend on the ability to create a strange orbit around the same magnet... I'm guessing speed might be an issue of it varies too greatly etc etc... I dunno I'm just musing.

We harness magnetic energy all the fucking time. Do you understand how a hydroelectric dam works?!?

krakus did u read my first post in this thread?

creating a system which is in constant motion is not useful unless all u want to do is look at it.

if u want to use it as a source of energy, then it will cease to be in constant motion.

Do you understand this point?

Yeah do you understand how the HYDRO comes into play in that particular example?

repeating incase u missed it coz we posted at same time:

Yes I understood that point and I agree, but if you use two forces, gravity and magnetism, I wonder about the possibility of have a better than 100% retrun in kinetic movement...

if you understood the point, let alone agreed with it, then you wouldn't make such a suggestion.

No matter what configuration you use, or which forces you harness, you cannot create energy out of nothing.

I don't understand why you think combining gravity and magnetism would somehow allow you to violate reality.
