I would like to build an air coil that will create a flux field, which will in turn induce a closed loop coil, that results in an equal and opposite force. The power source is an array of PV cells hooked up in series or parallel which ever will give the air coil the greatest/strongest magnetic field. If I understand this correctly series will increase the amperage and parallel will increase voltage. The closed loop coil may or may not be constructed with a soft iron core.(adsbygoogle = window.adsbygoogle || []).push({});

To make one of these arrays I'm starting off with 6 PV cells that are rated at 1/2V @ 720ma each. How do I calculate the optimum length of wire for the air coil and the closed loop coil?

This question may be too easy to answer for you EEs, so I would rather understand the calculations involved than be given the answer, since the design may alter in the prototyping process it would be better for me to understand what I'm doing.

Thanks
