Discussion Overview

The discussion revolves around the feasibility of using the force exerted by two magnets to turn a wind turbine for electricity generation. Participants explore the mechanics involved and clarify the distinction between wind turbines and windmills.

Discussion Character

  • Exploratory, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant inquires whether attaching a magnet to a wind turbine blade and using another magnet to push it could generate electricity.
  • Another participant questions the nature of the inquiry, suggesting it may relate to either a functional wind turbine design or the concept of a perpetual motion machine.
  • There is a clarification that at least one component of the turbine must be a coil to allow for current flow, rather than both being permanent magnets.
  • Discussion includes a note that perpetual motion machines are not allowed as a topic due to their physical impossibility.
  • One participant expresses confusion about the ban on perpetual motion discussions and seeks further clarification.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the original question, and there are competing views regarding the feasibility of using magnets in the proposed manner. The discussion remains unresolved regarding the practical application of magnets in wind turbine design.

Contextual Notes

There are limitations in the understanding of the mechanics involved in using magnets for electricity generation, particularly regarding the necessary components for current flow and the implications of perpetual motion concepts.

Hi, this is my first time on the forums and I'm sorry if this is in the wrong place. I was wondering if I got a windmill and 2 rare Earth magnets can I stick one magnet to the blade of the fan and then use the other magnet to push the windmill to generate electricity? -Thanks

oops i meant wind turbine not a windmill lol sorry bout that
 
Hi ArcticWolf 11 welcome to PF!

I am not certain exactly what you are asking. I am not sure if you are asking if a wind turbine could be formed using a permanent magnet for both the rotor and the stator, or if you are asking about a perpetual motion machine.

If the first, then you need at least one of either the rotor or the stator to be a coil rather than a permanent magnet so that you can get a loop for the current to flow through.

If the second, then you should be aware that perpetual motion machines are a banned topic here.
 
oh.. i didn't know they were banned, and why are they a banned topic here? -sorry :(

perpetual motion machine discussions are banned because they are not physically possible

if you are not talking about something that is self powering, then explain more clearly what you were thinking about :smile:cheers
