I have tried to make an AC-generator to create a voltage over an LED. The circuit diagram can be seen in the attached figure. It consists of four coils attached in series and a rotating magnet in the middle. I first tried with only two of the coils on either sides of the magnet, and got 1 volt. I then tried adding the other two coils and also got 1 volt, but I need at least 2 volts to make the LED work. I suspect this was caused by a phase shift of the voltage of the two other coils, which gives 0 volts when the first two give 1 volts.

I suspect that adding a capacitor should make a phase shift and add the voltages from both pairs of coils so I can get 2 volts. I am just woundering if I am going in the right track. Will adding a capacitor as indicated in the circuit diagram give me the result I want of giving the same phase to both pairs of coils?
