Wind Turbine DIY Project for School - Steel Plate vs Non Magnetic Plate

Click For Summary

Discussion Overview

The discussion revolves around the construction of a wind turbine for a school project, specifically comparing the use of steel plates versus non-magnetic plates for mounting magnets. Participants explore the implications of these materials on the power output of the turbine, focusing on concepts related to magnetic fields and generator efficiency.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant questions the choice of steel plates, suggesting that they may concentrate the magnetic field and thus increase the generator's power output.
  • Another participant proposes the idea of using smaller magnets in conjunction with steel plates to enhance performance, although they express uncertainty about this approach.
  • A participant references an article that claims steel hubs can confine magnetic field lines, potentially explaining why steel might be advantageous for power generation.
  • There is a repeated inquiry about whether steel plates actually increase the power of the turbine, indicating a need for clarification on this point.

Areas of Agreement / Disagreement

Participants express differing views on the effectiveness of steel plates versus non-magnetic plates, with no consensus reached on which material is superior for increasing turbine power.

Contextual Notes

Some assumptions regarding the properties of magnetic fields and the specific designs of wind turbines are not fully explored, leaving open questions about the optimal configurations for performance.

i don't know if i am in right part of forum.

i want to build some sort of wind turbine for a school project. all the diy project are 6 or 9 coils with 8 or 12 magnets. the coils are on non magnetic board and the magnets on steel plate.
why on steel, the steel plate increase the total power of generator, like concentrate the magnetic field? is not better to mount the magnets on non magnetic plate to?
 
Physics news on Phys.org
I could see using smaller magnets and compensating by using steel plates to act as additional magnets. Not really sure though. Got a link to a DIY one?
 
this is an example. http://www.windenergy.nl/website/files/artikelen/AXIAL_FLUX_HowItWorks.pdf .
my q is if seel plate increase or no the power of the turbine

From the article it says the magnetic field lines are confined by the steel hub the magnets are attached to. This might be the reason. That and steel is strong and relatively cheap.
