hi,
i need to build sheet fanner. (it is called sheet seperator too)
as shown at attached image, sheet fanner is magnetically separating the top sheets.
i must build many coils to create magnetic force.
how i design coils ? is there any formula or any kind of help designing coils ?
thickness of copper cable ? voltage ? ampere ?
i don't know how to start building coils.
i do not want to use Neodymium magnet or permanent magnet because DIY coils are cheaper.
thanks
