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

[dinablaster]

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?

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.

I would like to provide some insight on the use of steel plates versus non-magnetic plates in wind turbine DIY projects.

Firstly, it is important to understand the purpose of the steel plate in this project. The steel plate is used to create a magnetic circuit for the magnets, allowing them to be more efficient in generating electricity. This is because steel is a ferromagnetic material, meaning it can be magnetized and will retain its magnetism. This helps to concentrate and direct the magnetic field created by the magnets, resulting in a more powerful and efficient generator.

On the other hand, using a non-magnetic plate such as aluminum or plastic may not have the same effect. These materials are not ferromagnetic and therefore will not contribute to the magnetic circuit. This could result in a weaker magnetic field and lower power output from the generator.

In addition, using a non-magnetic plate may also introduce unwanted interference to the magnetic field, reducing its strength and efficiency. This is because non-magnetic materials can still interact with magnetic fields, causing disruptions and distortions.

In conclusion, while it may seem counterintuitive to use a steel plate in a DIY wind turbine project, it is actually the most effective choice for generating electricity. The steel plate helps to concentrate and direct the magnetic field, resulting in a more powerful and efficient generator.
