The world needs a new source of energy, an unspillable source.

wind turbine generator?

I’m making a small wind turbine for a science project. It doesn’t need to produce a lot of electricity, just enough to register on a multimeter. I just need to know: For the generator, are magnets and coils the only things I need for the turbine to generate electricity? Or is there something else I’m missing? I just need this cleared up.
