A permanent magnet produces energy?

level zero logic


1.The force of repulsion of a magnet is as static (but different no racism please) as the force of a mountain lake


2.The magnets of a brushless motor produce energy instead and in power,
replacement is integral

3. to suspend or magnetically stick a Kilo costs 9Kwh / year, even in static it is not free


Edit 01/03/2016 Moderation Capt_Maloche


a "permanent magnet" is aptly named, it provides a force,
To produce energy from a force, it must be varied to create "work"

So either, a permanent magnet does not produce energy

1 / if you do not move your lake, all like it, the forces do not work so no energy at the end

2 / where are you coming from? oO

3 / and if I hang this kilo on a suction cup, then the suction cup also produces 9kWh / year?

Logic mode zero on:

If you observe a kid on a trampoline, you will see that he is able to jump much higher than without, so the trampoline produces energy which is added to that of the kid ... 8)

Logic mode zero off ...

Hi achernar

1 yes
2 to the equivalence between the 2 by similarity
3 original! Yes

I seek points of departure with various reasonings to support what I assert

What's your problem? : Mrgreen:

The trampoline stores energy.

For my part I try to understand your reasoning in order to have a healthy discussion;) And it is not I who will blame you for showing curiosity :)
In addition you are right, there is energy that is exchanged between the plate and the magnet, except that this energy is in both directions so the overall energy of the system is constant. Because as for gravity one acts on the other and vice versa in equal parts. So yes there is a lot of energy in games, but it is an exchange. We do not create energy because energy is a finite quantity that we exchange like DBZ cards. If you want more you can fly elsewhere but there will always be the same number in the end overall. In the same way, the energy billing of an electromagnet is zero.

As a reminder, "producing" energy is an ambiguous term because in reality we never create energy, we take it elsewhere in another form. "nothing is lost nothing is created everything is transformed"

The trampoline restores (with a slight loss) the kinetic energy of the fall, which would otherwise be lost in shock or shock absorption.

To stop, the trampolinist cushioned his fall by bending his knees.

My example of a trampoline was intended to demonstrate the absurd and by analogy with the magnet ...
