Perpetual Battery with Pickup Coil and Magnents

[Blakeasd]

Hello,

I recently was thinking about an idea for a perpetual battery. I have an extremely limited amount of Physics knowledge (just a Conceptual Physics [Algebraic Physics] class) as I am still in high school. Does anyone know if this would work:

1. Have a tube
2. Wrap the tube in copper wire (so the tube has a copper coil over it)
3. Have a magnet on one side of the tube (-) and have another on the other end (+)
4. Have yet another magnet (in a cylindrical like shape) inside the tube
5. The magnet would go back and forth inside the tube

My questions are:

Would the magnet actually go back and forth or would it be in equilibrium?

If the magnet was in equilibrium would there be a way to alternate the end magnets so that the magnet would actually go back and forth?

If the magnet were to move, would a measurable amount of electricity be produced even with an extremely long tube and extremely powerful magnets?

Thanks!

Perpetual motion and over unity devices are not allowed for discussion per PF rules.
And no, it wouldn't work. Both concepts are impossible.

If you made a magnet inside move(give it some non zero initial velocity) then it'd produce some current while its kinetic energy gets dissipated. Then it'd eventually(rather quickly) stop at some equilibrium point and stay there.

The thing to remember is that inducing a current by moving a magnet produces a force on it acting against the movement.

Your "tube battery" is kinda built with the same principle on which bicycle dynamos work. You can't just spin it once for it to produce infinite energy, you have to keep spinning it(i.e.put some mechanical energy into it that gets converted into electricity).

And no, there's no good way of alternating the top/bottom magnets, as doing so requires more energy than you'd get from the magnet inside.


It's still a good idea, though. They use something very similar in those flashlights that you charge up by shaking them up and down.

Perpetual motion and free energy are banned topics here on the PF. They are listed in the Banned Topics section of the Rules link at the top of the page. This thread is closed.

Hello,

Thank you for sharing your idea for a perpetual battery. While it is always exciting to explore new ideas and concepts, it is important to approach them with a critical and scientific mindset.

Firstly, it is important to note that the concept of a perpetual battery goes against the laws of thermodynamics, which state that energy cannot be created or destroyed, only converted from one form to another. This means that a perpetual battery, which would continuously generate energy without any external input, is not possible.

In regards to your proposed design, there are a few things to consider. The movement of the magnet inside the tube would depend on the strength and positioning of the magnets, as well as the resistance of the copper wire. It is possible that the magnet may reach an equilibrium position where it does not move, but this would also depend on the external forces acting on the system.

Additionally, even if the magnet were to move, the amount of electricity produced would depend on the strength of the magnets, the length of the tube, and the resistance of the wire. It is unlikely that this setup would produce a significant amount of electricity, especially when compared to other energy sources.

In conclusion, while your idea is interesting, it is not a feasible solution for a perpetual battery. It is important to continue learning and exploring new ideas, but also to approach them with a scientific understanding and critical thinking. Keep asking questions and seeking knowledge, and who knows, you may come up with the next groundbreaking idea!
