I need help figuring out the best way to do the following. And i have been searching and apparently I don't know the proper way to phrase this to find the information on google/instructables. What I need - a small surface that is magneticly reactive, to be able to Write with a magnet. It also needs to be able to be erased, probably also with a magnet. I want it to be decently small, and I am sure there is material out there, but i don't know what it is. And no I dont want a dry erase board. Think of the Magnadoodle, where it would react to what is being drawn with the magnet, but i wnat something that is more like a Slate, and not a series of pockets that have a certain amount of filaments that react to the magnet. I am sure there is some kind of material like this out there. I just dont know what to call it, and i need to be able to make it decently small and thin. A basic idea, is like an impression pad. If you wrote something on the top sheet, or a couple of sheets of the pad, under the sheets, it would take an impression of it, (assuming it was written with a magnetic pen), you could then see what was written on the sheet originally, on the surface. Also it would need some way to be erasable so it could be used again. A concept like carbon paper, but with magnets. Please point me in the right direction, I am very hands on, and a long term DIYer, i just need to know what basic material i need to accomplish this. I know it exists, i just don't know what to call it.
