Rodin coil troubling me.

[aspardeshi]

Hello Friends,

I can build a rodin coil, but before building it, i have a doubt. I want the rodin coil to generate electricity for me by placing a neo sphere magnet in the centre, If I apply the coil ends to battery for neo sphere to rotate over the axis, how do i collect the current generated from the coil ? Help this noob.

Thanks in advance.
