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

AI Thread Summary
Building a wind turbine for a school project involves using coils and magnets, typically mounted on a non-magnetic board with magnets on a steel plate. Steel plates can enhance the generator's power by concentrating the magnetic field, which may lead to improved efficiency. While some suggest using non-magnetic plates for the magnets, the consensus leans towards steel due to its ability to confine magnetic field lines effectively. Additionally, steel is a strong and cost-effective material for this application. Ultimately, using a steel plate is likely beneficial for increasing the turbine's power output.

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.

Thread 'Need help understanding particle physics and quantum physics'

So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks

Thread 'Raman Spectroscopy help'

I am attempting to use a Raman TruScan with a 785 nm laser to read a material for identification purposes. The material causes too much fluorescence and doesn’t not produce a good signal. However another lab is able to produce a good signal consistently using the same Raman model and sample material. What would be the reason for the different results between instruments?
