Hi,
I'm in the process of making a magnet powered generator to mount on my bike. I've made this setup (see picture) to test the idea and am surprised to find that it generates only about 26 mV when rotating at high speed! I'm using a 2 mm thick neodymium magnet and a coil with app. 20 windings.
How can this be optimized to provide ~ 40 volts (!) ? Do I need to orient the coil differently relative to the magnet or is it mainly a question of more powerful magnets and more windings? Will it help adding an iron core to the coils or something similar?
Any insights appreciated
Greetings,
Jesper
