Dear Sir,

I am trying to turn a small metal cam that is inside of a plastic sealed
case. I am thinking that a electromagnet that shifts polarity could
push the disk in one direction and reversed turn it in the other. Is
this possible and if so who could help me to make such a device?

Thanks for the help
