This year I have designed various kind of motors that are made from PCBs. These designs have inspired me to try and create an electromagnet drawn on paper!
To draw the coil I have used conductive ink that created a much smaller resistance than if I used a normal 2B graphite pencil. I started out with 35 turns but the resistance still got to 2.4kohms, so I reduced the turns to 20 and got a 60 ohms independence.
As shown in the video, I managed to get some good results for attraction and repulsion. There is still some room for improving the "electromagnetic drawing." I can try to make the coils a little thicker to reduce the resistance as much as possible. I can also use thinner paper to get more flex and also try drawing it on both sides.
