Do magnets die ?

[deftron]

Couldn't magnets be used to make a perpetual motion machine
like a metal wheel with magnets surrounding it to keep it spinning indefinitely
or do they eventually loose their power ?

 

[Brackis]

Impossible to find a perfect balance of magnetic forces to keep the wheel spinning ad inifinitum. (this is coming from someone who is bad at physics)

 

[Bootprint]

It's the not magnets, but friction of the object moving them.

Yeah. That.

 

[edro]

Yes, you could. The problem is friction and gravity.

What you are thinking of is the inverse of what an electric motor is.

Generator?

Yes!!!

Wrong. A magnet exerting magnetic force on another magnet or a ferrous object will eventually lose its "energy."

And because of those two, heat.

 

[DXM]

Magnetic force is dependent on acceleration of the particle being acted on, so unless you can accelerate the object forever, it will eventually stop.

I think you need to draw a picture, I have no idea what you're talking about.

 

[Bootprint]

That's what windmills do.

 

[hdeck]

they lose their power

 

[Random Variable]

It will keep losing energy through friction, and since the magnets aren't actually doing any work, it will eventually stop ( I think ).

maybe a freebody diagram? haha

This is basically it

You fail at linking.
EDIT: nm, you actually fail at uploading.

indeed. don't the organized matereal that make a magnet polor slowly become .......unorganized.

not bad after 3 shots of crown royal with coke eh , I'm not evening making too many typo's yet.

What you have drawn is almost a motor but it will stop before it goes 1/8 of a turn. If you kept alternating the pulling and attracting magnets to be ever pulling then you'd have a motor. Motors need the input of energy to keep moving.

 

[Ornery]

Magnet Motors

• Contrary to the belief of some inventors, magnets are not a miraculous source of inexhaustible power. They have stored energy (put in when they were initially magnetized), but once that relatively small amount of energy is used up, they aren't magnets any more. Strike a magnet repeatedly with a hammer, and you can reduce its magnetization considerably. On the other hand, hold a rod of unmagnetized soft iron aligned with the earth's field, strike it repeatedly with a hammer, and you will find it has become magnetized by induction. And you didn't put much energy into it, did you?

Deja vuster.. I'm partaking of two shots of Crown Royal with Pepsi right now. You win but mine taste better.
