Wind turbine science project

Hi guys,

My friend and i want to make a wind turbine for our science project.
The design that we want to go with is the 3 bladed one with a single phase alternator.

In which there is a cylindrical magnet which has north and south on the curved side with 2 coppper coils on either side.

I have searched around for a magnet like this (attached) on australian sites and i cannot find one.this one is from england and shipping costs heaps.So do any of you guys know where we can buy one here in Australia.It is 20mm by 20mm with a 6mm hole in it.

Thanks in advance

Orestis
Ps-have any of you guys made one of these?

Not exactly to your dimensions, but they might be able to order a custom size.

Word of warning. If you intend using neodymium (rare earth) magnets be very careful. These magnets are much more powerful than ferrite magnets. It's easy to crush fingers when stacking rings.

How big do you want the blades it to be ?
This would help to determine the materials ..
