Generator Energy harvesting

This is first attempt to do a simple yet effective electricity generator for energy harvesting.
Normally generators is quite large and use double of magnets to shift North/South over Inductors, but with this design the number of Magnets are reduced to one for each winding.
Also due to no magnets are aligned close to each others opposite pole, stress on material is minimised.

Pls note I use Ø 0.25mm wire and 50 windings on each coil.
This gives an effective voltage of 2.5Vpp output. Load te
