I have an eInk tablet/reader (a Boox Go Color 7) and a cover for it. The cover uses magnets to both stick to the reader and to trigger the reader to wake up/sleep.
The cover is kind of terrible otherwise, so I’d like to make a replacement, but I’d like to keep the magnetic functionality. Is there a standard sort of magnet that gets used for this kind of application, or is it just “whatever the manufacturer happened to choose”?
If it makes a difference, the cover is roughly 0.1" thick, so the magnets must be pretty thin.
I had a kindle cover I don’t use so I cracked it open. Not an expert but I think it’s a tiny neodymium magnet, a 7mm circle a little under 1mm thick. I think this is big enough to trigger the kindle’s wake up function, but a separate magnet is used to keep the cover shut. I’ve accidentally triggered the wake up function a few times with weak external magnets, so you probably don’t need much as long as it’s placed properly for your e-reader
Hope this helps!
